Hongxu Jia 37dd8810df kernelsrc/perf: clean up package version while using kernel source 
If recipe inherits bbclass kernelsrc to use kernel sources,
the recipe should explicitly set ${KERNEL_VERSION} to ${PKGV}
in task do_package, otherwise package version (${PV} is usually
default 1.0) is not consistent with kernel source.

For example, there are 5 recipes in meta-openembedded to inherit
kernelsrc, but 4 recipes explicitly set PKGV.

meta-openembedded$ grep -e "setVar(.*PKGV.*KERNEL_VERSION" -e kernelsrc -rn *
meta-oe/recipes-kernel/intel-speed-select/intel-speed-select.bb:9:inherit kernelsrc
meta-oe/recipes-kernel/bpftool/bpftool.bb:8:inherit bash-completion kernelsrc kernel-arch
meta-oe/recipes-kernel/bpftool/bpftool.bb:44:    d.setVar('PKGV', d.getVar("KERNEL_VERSION").split("-")[0])
meta-oe/recipes-kernel/cpupower/cpupower.bb:8:inherit kernelsrc kernel-arch bash-completion
meta-oe/recipes-kernel/cpupower/cpupower.bb:32:    d.setVar('PKGV', d.getVar("KERNEL_VERSION").split("-")[0])
meta-oe/recipes-kernel/turbostat/turbostat.bb:98:    d.setVar('PKGV', d.getVar("KERNEL_VERSION").split("-")[0])
meta-oe/recipes-kernel/usbip-tools/usbip-tools.bb:25:inherit kernelsrc autotools-brokensep
meta-oe/recipes-kernel/usbip-tools/usbip-tools.bb:68:    d.setVar('PKGV', d.getVar("KERNEL_VERSION").split("-")[0])
meta-oe/recipes-kernel/spidev-test/spidev-test.bb:7:inherit bash-completion kernelsrc kernel-arch
meta-oe/recipes-kernel/spidev-test/spidev-test.bb:26:    d.setVar('PKGV', d.getVar("KERNEL_VERSION").split("-")[0])

This commit clean up the setting of PKGV, move it to kernelsrc.bbclass
for common use, the recipe (such as intel-speed-select) that inherited
kernelsrc will not be required to explicitly set ${PKGV} with
${KERNEL_VERSION}
