kmodloader: support loadable module parameters in modinfo
Current OpenWrt loadable modules embed details of parameters accepted on
loading, but these aren't shown to users. Enable modinfo to print this
information like most other distros. For example:
root@OpenWrt:/# modinfo mac80211
filename: /lib/modules/6.1.65/mac80211.ko
license: GPL
depends: cfg80211,compat
name: mac80211
vermagic: 6.1.65 SMP mod_unload MIPS32_R2 32BIT
parm: minstrel_vht_only (bool)
parm: max_nullfunc_tries (int)
parm: max_probe_tries (int)
parm: beacon_loss_count (int)
parm: probe_wait_ms (int)
parm: ieee80211_default_rc_algo (charp)
