ash: Unix-style paths, shell builtins and applets

Some shell builtins also exist as applets:  echo, printf, pwd and
test, for example.  If such an applet is referenced using a Unix-
style path, e.g. /usr/bin/echo, the applet should be run rather
than the builtin.  Instead the current code says:

   sh: /usr/bin/echo: file not found

Rearrange the tests in shellexec() so the correct behaviour occurs.

Actually, the error message was also incorrect due to a separate
bug.  Commit d71cb67ff (win32: revert special treatment of Unix-style
absolute paths) failed to allocate space on the stack so that the
command passed to tryexec() could have an extension added if
required.
