[OE-core] [PATCH 2/2] archiver.bbclass: fix do_ar_recipe error for bonnie++ and libsigc++-2.0

[Dengke Du]

When recipes name contains regular expression special characters, such as "++",
in this case, the re.compile function in do_ar_recipe can't recognize it, so we
should associate with re.escape to recognize the special characters in pattern.
