ipa-run-tests: add support of globs for test targets and ignores

ipa-run-tests expands arguments passed with their full paths. However,
it doesn't support expanding globs, so targets like 'test_ipa*' cannot
be specified.

Expand the code that replaces '--ignore foo' and 'foo' positional
arguments with support for '--ignore foo*' and 'foo*'.

This allows to reduce a number of additional steps in the CI pipeline
preparation.
