libarchive: Workaround mbsnrtowcs assertion failure on old glibc 

The CMake TarTest fails with the error

 mbsnrtowcs.c:116: __mbsnrtowcs: Assertion
  `status == GCONV_OK || status != GCONV_EMPTY_INPUT ||
   status == GCONV_ILLEGAL_INPUT || status == GCONV_INCOMPLETE_INPUT ||
   status == GCONV_FULL_OUTPUT' failed.

on very old glibc versions.  Work around the problem by pretending that
mbsnrtowcs does not exist.  Libarchive will fall back to mbrtowc.
