VolumeManager: don't use faccessat(AT_SYMLINK_NOFOLLOW)
Don't use faccessat(AT_SYMLINK_NOFOLLOW). In Android, AT_SYMLINK_NOFOLLOW
is ignored. In glibc, it returns counter intuitive results when a
symbolic link is encountered, returning true all the time even though
an open(O_NOFOLLOW) will eventually fail.
Instead, stat the file and check to see if it's a regular file,
not a directory or symlink or some other weirdness.
In addition, fix a bug where isAsecInDirectory would return
true ("-1") if the asec directory didn't exist. It should return
false.
