[PATCH] ktest: Accept quoted bad term in git bisect output

["Ricardo B. Marlière (SUSE)" <ricardo@marliere.net>]

Git commit 0c0f93e7fa64 ("bisect: print bisect terms in single quotes")
changed the completion message to put single quotes around the bisect term.
run_git_bisect() only recognizes "is the first bad commit", so it misses
completion and continues the bisect loop with newer Git.

Accept both quoted and unquoted forms to retain compatibility with older
Git versions.
