ti-jailhouse: Fix buildpaths QA warning and cleanup

Add -ffile-prefix-map flags to KCFLAGS to remove build path
references from kernel module compilation, ensuring reproducible
builds and preventing absolute path leakage in binaries.

inherit module-base kernel-module-split for building kernel modules

move V=1 into EXTRA_OEMAKE and remove overriding do_compile()

This resolves buildpaths QA warnings during packaging.
