Bumps signal-hook from 0.3.18 to 0.4.5.

Changelog

Sourced from signal-hook's changelog.

0.4.5

• pipe::register_raw now really sets close-on-exec (FD_CLOEXEC) on the file descriptor, for both pipes and sockets (#206).
• Removed the 32-bit Android sigemptyset/sigaddset fallback, which panicked in emulate_default_handler (#207). Android below API 21 is no longer supported.

• Documentation about SIGBUS (#204).

0.4.3

• Don't exclude .c files from release package.
