checkpatch: Avoid some false positives for TABSTOP declaration test

[Joe Perches]

Using an open bracket after what seems to be a declaration
can also be a function definition and declaration argument
line continuation so remove the open bracket from the
possible declaration/definition matching.

e.g.:
	int foobar(int a;
		   int *b[]);
