kheaders: explicitly validate existence of cpio command
If the cpio command is not available the error emitted by
gen_kheaders.so is not clear as all output of the call to cpio is
discarded:
GNU make 4.4:
GEN kernel/kheaders_data.tar.xz
find: 'standard output': Broken pipe
find: write error
make[2]: *** [kernel/Makefile:157: kernel/kheaders_data.tar.xz] Error 127
make[1]: *** [scripts/Makefile.build:504: kernel] Error 2
GNU make < 4.4:
GEN kernel/kheaders_data.tar.xz
make[2]: *** [kernel/Makefile:157: kernel/kheaders_data.tar.xz] Error 127
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [scripts/Makefile.build:504: kernel] Error 2
Add an explicit check that will trigger a clear message about the issue:
CHK kernel/kheaders_data.tar.xz
./kernel/gen_kheaders.sh: line 17: type: cpio: not found
The other commands executed by gen_kheaders.sh are part of a standard
installation, so they are not checked.
