riscv: signal: fix signal_minsigstksz
[ Upstream commit 564fc8eb6f78e01292ff10801f318feae6153fdd ]
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.
