ash: simplify spawning during forkshell

spawn_forkshell() uses mingw_spawn_proc() to start the child shell.
mingw_spawn_proc() then calls mingw_spawn_1() which determines
that "sh" is an applet, thus calling mingw_spawn_applet() which
finally calls spawnveq().

Not only is this convoluted it also won't work if PREFER_APPLETS
and SH_STANDALONE aren't enabled.

Simplify matters by adding a new function, mingw_spawn_forkshell(),
which is tailored for just this case.
