riscv: signal: fix signal_minsigstksz

Browse source 
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.

Fixes: e92f469b07 ("riscv: signal: Report signal frame size to userspace via auxv")
