vendor/lineage: Remove kernel.mk headers generation

Browse Source 
*) This has been deprecated by the bp mobule
   generated_kernel_headers.

*) To build with kernel headers, do this:
   LOCAL_HEADER_LIBRARIES += generated_kernel_headers
   Or for soong targets:
   header_libs: [ "generated_kernel_headers" ],

# Install kernel (uapi) headers.
#
# The dependency file serves two purposes:
# - It is a stamp indicating when the headers were last installed.
# - It contains a rule to regenerate itself when any kernel header
# files change. This rule is identical to the rule emitted by
# GCC using the M/MM flags.
#
# Note that the location of installed kernel headers changed when the
# kernel uapi system was introduced in 3.7. Unfortunately, it is not
# sufficient to test whether the uapi directories exist because some
# kernels backport patches that contain uapi headers. So we look for
# the string "version_h" in the kernel makefile which was introduced
# as a part of the uapi system (commit d183e6f570f3).
