checksrc: fix SPACEBEFOREPAREN for conditions starting with "*"

The open paren check wants to warn for spaces before open parenthesis
for if/while/for but also for any function call. In order to avoid
catching function pointer declarations, the logic allows a space if the
first character after the open parenthesis is an asterisk.

I also spotted what we did not include "switch" in the check but we should.

This check is a little lame, but we reduce this problem by not allowing
that space for if/while/for/switch.
