x86/kernel: increase kcov coverage under arch/x86/kernel folder
Currently kcov instrument is disabled for object files under
arch/x86/kernel folder.
For object files under arch/x86/kernel, actually just disabling the kcov
instrument of files:"head32.o or head64.o and sev.o" could achieve
successful booting and provide kcov coverage for object files that do not
disable kcov instrument. The additional kcov coverage collected from
arch/x86/kernel folder helps kernel fuzzing efforts to find bugs.
