normal cbb79f0472 signal.c: avoid repeated disable/enable interrupt
We only install system-level signal handlers during init (before any
threads or user code is running), so there's no need to repeatedly
enable/disable the interrupts at that time.  We also do not change
system-level sig handlers once user-level code is running.

This saves about 20 syscalls at startup and makes the executable
smaller (numbers from 32-bit x86):
