[Buildroot] [PATCH 1/1] package/samba4: update samba4-cache.txt for fcntl flags check

[Bernd Kuhls]

Checking whether fcntl supports setting/geting hints : not found
..
Cross answers file /home/giuliobenetti/autobuild/run/instance-2/output-1/build/samba4-4.14.2/cache.txt is incomplete

Samba4 has added a check for fcntl F_{G,S}ET_RW_HINT /
F_{G,S}ET_FILE_RW_HINT handling since:
https://gitlab.com/samba-team/devel/samba/-/commit/5084a69de14f24e9d804998580eefcba773fdd5a

Which is supported by the Linux kernel since 4.13 in commit
c75b1d9421f80f41 (fs: add fcntl() interface for setting/getting
 write life time hints), so add it to the cache file.
