mktests.sh patches

[Tim Van Holder]

A few patches:
 - support DOS paths when determining as_me & base name
   (minor, as it's normally run from the makefile,
    which uses forward slashes)
 - use $base.tat, not $as_me.tat (is mktests.sh.tat, and
   DOS doesn't support multiple dots). I suppose using
   'mktests.tat' would be better (as now we need to use
   rm *.tat in the trap code, which might remove files we
   wanted to keep)
 - use '|| exit 0' instead of '; :' to ensure success in
   the subshell when creating acdefuns/audefuns. For some
   reason, the '; :' had no effect for me - but using
   '|| exit 0' should be equivalent, no?
