Konstantin Belousov c5637b8be8 rtld: ignore fstatfs(2) errors when checking MNT_NOEXEC flag 
File descriptor we operate on might reference something that is not a
file, e.g. shmfd.  In this case, we cannot check MNT_NOEXEC in
principle.

If fstatfs(2) caused some failure on normal filesystem, then typical
expectation is that read or mmap of this file would also fail.  If not,
mmap(2) PROT_EXEC on MNT_NOEXEC filesystem returns EACCES.
