[Libguestfs] [PATCH] Add 'make installcheck' rule to test installed packages.

[Richard W.M. Jones]

This is my proposed alternative to the complicated test framework
(https://www.redhat.com/archives/libguestfs/2015-August/msg00022.html).

In this patch, when we want to run tests on installed packages we just
copy in the installed binaries over the source directory, and run the
test suite as normal.  This is basically the same as the current (not
used) contrib/make-check-on-installed.pl script, but with a bunch of
fixes.
