ash: only catch unexpected exceptions in PS1 expansion
Commit d1a2fa2a4 (ash: catch error in arithmetic expansion in PS1)
catches all exceptions raised by expandarg(). Some exceptions, such as
the EXEXIT raised when command expansion is used, are expected:
export PS1='$(echo "$ ")'
These should be processed normally or the shell hangs at the prompt.
