analyze-build: incorrect exit code when using --sarif and --status-bugs

[correctmost]

Description

I get an exit code of 0 when I run analyze-build --sarif --status-bugs on any codebase that has analyzer warnings. The exit code is non-zero if I use --plist or --sarif-html instead of --sarif.

The root cause seems to be that the bug reporting code only analyzes .plist and .html files for bug entries:

llvm-project/clang/tools/scan-build-py/lib/libscanbuild/report.py

Lines 348 to 357 in dd3c26a

	# get the right parser for the job.
	parser = parse_bug_html if html else parse_bug_plist
	# get the input files, which are not empty.
	pattern = os.path.join(output_dir, "*.html" if html else "*.plist")
	bug_files = (file for file in glob.iglob(pattern) if not empty(file))
	for bug_file in bug_files:
	for bug in parser(bug_file):
	if not duplicate(bug):
	yield bug

Could you please try 21 or main branch?
