unexpand: fix heap overflow

* src/unexpand.c (unexpand): Use xinmalloc() to gracefully
handle overflow.  Also use the runtime locale specific MB_CUR_MAX
rather than the worst case MB_LEN_MAX.
* tests/unexpand/mb.sh: Add a test case that fails in a default
glibc build with either MB_CUR_MAX or MB_LEN_MAX.
* NEWS: Mention the bug fix.
Reported by Michał Majchrowicz.
