util: New flag UNQUOTE_UNESCAPE_RELAX for unquote_first_word
The new flag UNQUOTE_UNESCAPE_RELAX preserves unrecognized escape sequences verbatim in unquote_first_word, either when it's a trailing backslash (similar to UNQUOTE_RELAX, but in this case keep the extra backslash in the output) or in the middle of a sequence string. Add unit test cases to ensure the new flag works as expected and to prevent regressions from being introduced. Tested with a follow up commit converting config_parse_exec() to start using unquote_first_word, in which case this flags makes it possible to preserve unrecognized escape sequences. Relevant bug: https://bugs.freedesktop.org/show_bug.cgi?id=90794
