Set the normal PID surrogate priority according to getpid() to avoid

	* glib/gthread.c: Set the normal PID surrogate priority according
	to getpid() to avoid errors for niced processes. (#86116)

	* gthread/gthread-impl.c, gthread/gthread-posix.c,
	gthread/gthread-solaris.c: Do the same for the posix/dce
	implementation. Solaris still needs to set priority of the main
	thread, because all unbound threads will schedule according to
	that value and it defaults to 0 (the minimal value).
