Fix host OS detection in configure.ac

squid_host_os was being left with the version appended. Which screwed all
the switch and if cases which depended on exact matching the name only.

This corrects the squid_host_os to not contain numeric versions and also
corrects several of the test cases using host_os instead of squid_host_os
or using squid_host_os with version digits.
