sternenseemann af60e68744 testers.hasPkgConfigModules: allow checking multiple pkg-config mods
This is very useful in conjunction with meta.pkgConfigModules, as the
new tester can use the list provided by this meta attribute as a default
value for moduleNames, making its usage in passthru.tests very
convenient.

For backwards compatibility, a shim under the old name is maintained
with a warning.
