Bump to latest upstream commit as it fixes a huge number of CVEs. Some
of them can't be linked to a given commit (e.g.
https://github.com/ckolivas/lrzip/issues/67). Moreover, upstream does
not plan to tag a new release any time soon:
https://github.com/ckolivas/lrzip/issues/99

- Fix CVE-2017-8842: The bufRead::get() function in libzpaq/libzpaq.h in
  liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial
  of service (divide-by-zero error and application crash) via a crafted
  archive.
- Fix CVE-2017-8843: The join_pthread function in stream.c in
  liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial
  of service (NULL pointer dereference and application crash) via a
  crafted archive.
- Fix CVE-2017-8844: The read_1g function in stream.c in liblrzip.so in
  lrzip 0.631 allows remote attackers to cause a denial of service
  (heap-based buffer overflow and application crash) or possibly have
  unspecified other impact via a crafted archive.
- Fix CVE-2017-8845: The lzo1x_decompress function in lzo1x_d.ch in LZO
  2.08, as used in lrzip 0.631, allows remote attackers to cause a
  denial of service (invalid memory read and application crash) via a
  crafted archive.
- Fix CVE-2017-8846: The read_stream function in stream.c in
  liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial
  of service (use-after-free and application crash) via a crafted
  archive.
- Fix CVE-2017-8847: The bufRead::get() function in libzpaq/libzpaq.h in
  liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial
  of service (NULL pointer dereference and application crash) via a
  crafted archive.
- Fix CVE-2017-9928: In lrzip 0.631, a stack buffer overflow was found
  in the function get_fileinfo in lrzip.c:979, which allows attackers to
  cause a denial of service via a crafted file.
- Fix CVE-2017-9929: In lrzip 0.631, a stack buffer overflow was found
  in the function get_fileinfo in lrzip.c:1074, which allows attackers
  to cause a denial of service via a crafted file.
- Fix CVE-2018-5747: In Long Range Zip (aka lrzip) 0.631, there is a
  use-after-free in the ucompthread function (stream.c). Remote
  attackers could leverage this vulnerability to cause a denial of
  service via a crafted lrz file.
- Fix CVE-2018-11496: In Long Range Zip (aka lrzip) 0.631, there is a
  use-after-free in read_stream in stream.c, because decompress_file in
  lrzip.c lacks certain size validation.

Also:
 - update indentation of hash file (two spaces)
 - drop patch (already in version)
 - manage host-nasm dependency which is enabled by default and has been
   fixed by:
