test/common: Fix matching on core dump's name

find's -name doesn't work with regexes hence the applied pattern
didn't match on plain "core" name (as the expression would suggest to
match on). Replace it with additional shell patterns to include some
additional common core_patterns - this is relevant for the tests which
may be run indepdendently from autotest.sh and still use core_pattern
with its default setting.
