Fix an fs_spec test under FreeBSD and a symlinked home directory.

Browse Source 
It turns out the FreeBSD 10 VM has a symlink for the home directory to
/usr/home.  Unfortunately, this breaks the test as arg[0] may not have
the symlink resolved, but the path returned from the exe() call will.
As a result, the comparison fails, even though the result is correct.

Let's fix this by running the absolute path through exe() too, and then
comparing the results.
