kernel-arch: drop CCACHE from KERNEL_STRIP definition

Building linux-yocto with ccache enabled results in the 'command not
found' error, because kernel-yocto.bbclass passes the KERNEL_STRIP
as a single value, whic is then interpreted as a command name.

ERROR: Fatal errors occurred in subprocesses:
[Errno 2] No such file or directory: 'ccache aarch64-linaro-linux-strip': Traceback (most recent call last):
  File "/home/lumag/Projects/RPB/build-rpb/conf/../../layers/openembedded-core/meta/lib/oe/utils.py", line 288, in run
    ret = self._target(*self._args, **self._kwargs)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Fixes: 03973c8c1c93 ("kernel: Add kernel specific STRIP variable")
