lib/mbsalign: abort() when non-expected case is encountered

Fixes the following compiler warning (9 occurrences), and makes program
to crash if mbsaligh() is called with unexpected align value (which
would be programming error).

../lib/mbsalign.c:260:7: warning: switch missing default case [-Wswitch-default]
