testcommon: add require_mods method and use it

This cuts down on lines of code in individual test cases and
fixes some misnamed error messages by using "$0" consistently.

This will also provide us with a method of swapping out
dependencies which provide equivalent functionality (e.g
"Xapian" SWIG can replace "Search::Xapian" XS bindings).
