module load: attempt to load modules from /vendor

Use TW_LOAD_VENDOR_MODULES := "module1.ko module2.ko modulen.ko"
in BoardConfig to have TWRP attempt to load kernel modules during
startup. For fastboot ramdisks, TWRP will attempt to load from
the ramdisk from /vendor/lib/modules. You can have the build
system copy the modules to
$(TARGET_RECOVERY_ROOT_OUT)/vendor/lib/modules/1.1
Otherwise in recovery in boot mode, TWRP will attempt the following:
check /lib/modules (ramdisk vendor_boot)
check /lib/modules/N.N (ramdisk vendor_boot)
check /lib/modules/N.N-gki (ramdisk vendor_boot)
check /vendor/lib/modules (ramdisk)
check /vendor/lib/modules/1.1 (ramdisk prebuilt modules)
check /vendor/lib/modules/N.N (vendor mounted)
check /vendor/lib/modules/N.N-gki (vendor mounted)
