Andrew Deason e07768aaf7 tests: Introduce afstest.pm
Create a perl module for some generic common code for our tests
written in perl: afstest.pm. With this commit, the module just
contains a couple of functions to calculate paths in our src and obj
trees (src_path(), obj_path()), analogous to afstest_src_path and
afstest_obj_path in our C helper library, libafstest_common.la.

Convert all existing perl test code that uses C_TAP_SOURCE/C_TAP_BUILD
to use these new functions.
