cmd/compile: fix ICE with parenthesized builtin calls

Browse source 
CL 419456 starts using lookupObj to find types2.Object associated with
builtin functions. However, the new code does not un-parenthesized the
callee expression, causing an ICE because of nil obj returned.

Un-parenthesizing the callee expression fixes the problem.

Fixes #63436
