Find parallel in more locations

Some distributions append or prepend “moreutils” to the parallel command
with a hyphen to distinguish it from the GNU version of parallel, such
as Arch Linux [1]. To facilitate testing on such platforms (for example
to test backup-utils with upcoming versions of rsync and newer Linux
kernel versions), this adds support for finding parallel in those
locations.
