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):

after: 2815022 12100 30552 2857674 2b9aca ruby
* signal.c (install_sighandler): remove rb_disable_interrupt and
rb_enable_interrupt calls
(init_sigchld): ditto
(Init_signal): disable and enable interrupt once around all
install_sighandler and init_sigchld to reduce syscalls at start
