David Steele 11c7c8fabb Remove pgbackrest test user.
This user was created before we tested in containers to ensure isolation between the pg and repo hosts which were then just directories.  The downside is that this resulted in a lot of sudos to set the pgbackrest user and to remove files which did not belong to the main test user.

Containers provide isolation without needing separate users so we can now safely remove the pgbackrest user.  This allows us to remove most sudos, except where they are explicitly needed in tests.

While we're at it, remove the code that installed the Perl C library (which also required sudo) and simply add the build path to @INC instead.
