i#8008 format: Remove non-UTF8 characters

[derekbruening]

Removes non-UTF8 characters from tools/runjob.c.
These crash clang-format-diff and are blocking PR #8009.
Also fixes non-UTF8 characters found in two other files while at it.

Issue: #8008

[bin-wang]

I scanned the repo and found 2 other files that contain non-UTF8 characters:

dynamorio/suite/tests/security-win32/sd_tester.c

Lines 132 to 133 in 4fe1106

	/* disabling b/c messes up the print: "success" comes out as "Ðuccess" */
	buffer_test("crtheap");

and

dynamorio/tools/DRinstall/ShellInterface.cpp

Line 221 in 4fe1106

AfxMessageBox (“Save failed!”);

They are not blocking #8009 but should we remove those as well?

May as well: I added them to this PR to fix all at once.
