Kyle Evans e0f14ecf60 vt: resolve conflict between VT_ALT_TO_ESC_HACK and DBG
When using the ALT+CTRL+ESC sequence to break into kdb, the keyboard is
completely borked when you return. watch(8) shows that it's working, but
it's inserting escape sequences.

Further investigation revealed that VT_ALT_TO_ESC_HACK is the default and
directly conflicts with this sequence, so upon return from the debugger
ALKED is set.

If they triggered the break to debugger, it's safe to assume they didn't
mean to use VT_ALT_TO_ESC_HACK, so just unset it to reduce the surprise when
the keyboard seems non-functional upon return.
