ash: only reset ANSI emulation in interactive loop

Commit 54d2ea4b4 (ash: reset ANSI emulation at prompt) worked
around a problem with MSYS2 applications.  This seems to have
been fixed in more recent versions of MSYS2 but there's still
value in retaining the workaround for other such cases.

However, the call to reset ANSI emulation is probably being made
more often than necessary.  Move it out of setprompt_if() and into
the main shell interactive loop.
