testsuite: Use -fno-report-bug in gcc.dg/plugin/

Certain downstream compilers (for example, in Fedora) default to
-freport-bug.  The extra output breaks the following tests.  We can use
-fno-report-bug to fix that.  Patch verified with:

$ make check RUNTESTFLAGS='--target_board=unix\{,-freport-bug\} plugin.exp'

gcc/testsuite/ChangeLog:

	* gcc.dg/plugin/crash-test-ice-sarif.c: Use -fno-report-bug.  Adjust
	scan-sarif-file.
	* gcc.dg/plugin/crash-test-ice-stderr.c: Use -fno-report-bug.
	* gcc.dg/plugin/crash-test-write-though-null-sarif.c: Use
	-fno-report-bug.  Adjust scan-sarif-file.
	* gcc.dg/plugin/crash-test-write-though-null-stderr.c: Use
	-fno-report-bug.
