app-portage/iwdevtools: backport tests fix for repos missing masters

May also have caused issues in other situations in the future,
so it's good to fix here rather than just fix the repo's metadata.

+Subject: [PATCH] tests: relax globs for some stderr output checks
+
+portage may add noise to these depending on the system, e.g.
+
+!!! Repository 'gentoo' is missing masters attribute in '/var/db/<snip>
+!!! Set 'masters = iwdevtools' in this file for future compatibility
+
+But these tests are only checking if our own expected error is there,
+the rest is not important.
