8263564: Consolidate POSIX code for runtime exit support: os::shutdown, os::abort and os::die

[dholmes-ora]

A trivial refactoring with zero functional changes.

The runtime exit code (os::shutdown, os::abort and os::die) on POSIX platforms is almost identical - Linux has one extra action in os::abort. This code should be shared via os_posix.cpp (note os::exit is already shared via os_posix.inline.hpp).

Testing:

• GHA
• Tiers 1-3

Thanks,
David
