6.12-stable review patch. If anyone has any objections, please let me know.

commit 564fc8eb6f78e01292ff10801f318feae6153fdd upstream.
The init_rt_signal_env() funciton is called before the alternative patch is applied, so using the alternative-related API to check the availability of an extension within this function doesn't have the intended effect. This patch reorders the init_rt_signal_env() and apply_boot_alternatives() to get the correct signal_minsigstksz.
