Looks like it's enough to just add wrappers pointing to the
corresponding SYS_FSTATAT{,64} or SYS_NEWFSTATAT syscall. Add a test to
verify that assumption which checks that the returned stat data matches
what is returned by Stat/Lstat.

Also add the AT_NO_AUTOMOUNT constant which may be used for the flags
parmeter.
