Update CI

This updates us from ubuntu-22.04 to ubuntu-24.04, removes some dead
code, and ensures we compile without network access in more places.

Note that the binary we're using for GCC 5.4 appears to require
ubuntu-22.04 and that this leaves updating the bootstrap CI for another
time.

ChangeLog:

	* .github/glibcxx_ubuntu64b_log_expected_warnings: Adjust
	expected warnings.
	* .github/log_expected_warnings: Likewise.
	* .github/workflows/ccpp32alpine.yml: Update from ubuntu-22.04
	to ubuntu-24.04 and remove
	ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION.
	* .github/workflows/ccpp.yml: Likewise, compile without network
	access in more places, and remove commented-out warnings check
	in asan builder.
