[ Upstream commit 6e58e0173507e506a5627741358bc770f220e356 ]
Commit 13e1df09284d ("kheaders: explicitly validate existence of cpio command") added an explicit check for `cpio` using `type`.
However, `type` in `dash` (which is used in some popular distributions and base images as the shell script runner) prints the missing message to standard output, and thus no error is printed:
$ bash -c 'type missing >/dev/null' bash: line 1: type: missing: not found $ dash -c 'type missing >/dev/null' $
For instance, this issue may be seen by loongarch builders, given its defconfig enables CONFIG_IKHEADERS since commit 9cc1df421f00 ("LoongArch: Update Loongson-3 default config file").
Therefore, use `command -v` instead to have consistent behavior, and take the chance to provide a more explicit error.
