[git commit] tests: mmap2: ignore permission denied errors on /dev/mem

[Mike Frysinger]

commit: http://git.uclibc.org/uClibc/commit/?id=386a22b920780077d882e051689e6a3a6c92682b
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

Non-root users can't open /dev/mem, so it makes it hard to pass.
Ignore that case.
