Add plain ~ expansion for Windows system in File::Glob

Previously in File::Glob, a plain ~ expansion will check
the $HOME environment variable, but that does not normally
exist on Windows systems. There is another variable that
holds the appropriate home path value, which is $USERPROFILE.

This adds a fallback to check $USERPROFILE when $HOME is
not there, the system does not support checking the password
file and the system is DOSISH.
