init.insmod.sh: Find modules in different directories

Browse source 
Currenlty, kernel modules are only looked for in /vendor/lib/modules/.
With this change, we enable kernel modules to be stored under paths that
contain the kernel version string e.g.
/vendor/lib/modules/5.10.31-gd527c4be4795-dirty/
This aligns better with the kernel build system.
