checkpatch: improve OPEN_BRACE test
Some structure definitions that use macros trip the OPEN_BRACE test.
e.g. +struct bpf_map_def SEC("maps") control_map = {
Improve the test by using $balanced_parens instead of a .*
Miscellanea:
o Use $sline so any comments are ignored
o Correct the message output from declaration to definition
o Remove unnecessary parentheses
