kernel: send user interrupt on page fault

I really should just rename interrupts to something else.

This is inspired by Plan9 and meant to make debugging easier, as the
dying process can take a stacktrace etc.

It kinda sucks that the default handler now depends on fprintf, which is quite
a bit of code, but whatever.
