[libvirt PATCH v2 1/8] syntax-check: Drop the shell's 'check for minus' rule

Apparently we've only had it because the -[ao] options weren't portable at the time, but according to https://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html both are defined in POSIX.1-2017 revision which is old enough for all our supported platforms to have adopted it already. Therefore, drop the rule.
