openbsd_pkg: Fix regexp matching crash (#3161)

Browse source 
When a package name contains special characters (e.g. "g++"), they are
interpreted as part of the regexp.

This can lead to a crash with an error in the python re module, for
instance with "g++":

    sre_constants.error: multiple repeat

Fix this by escaping the package name.
