tests: loosen expectations for external info-zip tool

In our test suite, we're verifying some archives by utilizing the
unzip(1) program provided by info-zip.org. Due to changes to info-zip,
our test case 59770 may fail on some systems as we expect it to spit out
error messages in a specific format. Loosen those restrictions to make
the test pass on more systems.
