kheaders: use `command -v` to test for existence of `cpio`
[ Upstream commit 6e58e017 ] Commit 13e1df09 ("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 9cc1df42 ("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.
