Two minor bug fixes:
* A specific check during test mode would emit a failure to stdout when
testing devel/py-setuptools27. It turns out that there's a file there
with a space in the filename. The filename was an argument for
/usr/bin//file and it wasn't escaped. The file in question had
parentheses too which the shell was trying to process. The fix was
to escape the filename in the /usr/bin/file command.
* The builders were mounting the source directory from "/usr/src", not
$sysroot/usr/src as intended. This potentially causes breakage when
the $sysroot reflects a different versions/release than the host
machine has (e.g. making FreeBSD 10.2 packages on FreeBSD 11-current).
Now the source directory mount is relative to profile's $sysroot.
