Some more minor cleanups

src/cmd/INIT/mamake.c:
- Remove a superfluous test for strict() mode; it's known to be
  true there. (re: 29ab3b1, 60bda12)

src/lib/libast/include/ast.h:
- Add safety parentheses for mb2wc() macro.

src/cmd/ksh93/tests/*.sh:
- Timing adjustments for very slow ksh binaries (as in, compiled
  with AddressSanitizer).
