[PATCH] gprofng: protect against standard library macros

[Andreas Schwab]

The CALL_UTIL macro can expand to an unparsable expression of the argument
is a macro, like with the new const-preserving standard library macros in
C23.

	* gprofng/src/collector_module.h (CALL_UTIL): Add parens to not
	expand its argument if it is a function-like macro.
