ash: improve expandstr()
The dash maintainer recently posted a fix for issues with expanding
PS1. These had already been fixed differently in BusyBox ash. Borrow
a couple of improvements:
- Use a single call to setjmp() to trap errors in both readtoken1()
and expandarg().
- In case of error set the prompt to the literal value of PS1 rather
than the half-digested nonsense in stackblock() which might include
ugly control characters.
