package/linux-tools: selftests: use KHDR_INCLUDES to locate the headers

Browse Source 
Since v6.7 [1], the KHDR_DIR variable isn't used anymore by the kernel
selftest Makefiles to locate the kernel headers. Instead, KHDR_INCLUDES
is used to specify their location. It was only available between v6.5
and v6.7.

Keep KHDR_DIR for compatibility with v6.5 to v6.7 kernels, while
KHDR_INCLUDES is used by both pre 6.5 and post 6.7 kernels.

Let's pass it with the "-isystem" flag, as is done in the default values
used in the selftest makefiles.
