perf: fail if src path does not exist

Browse Source 
A missing src directory from a broken kernel recipe resulted
only in a warning:

WARNING: copyfile: stat of /home/builder/src/tmp-glibc/work-shared/target/kernel-source/tools/arch failed ([Errno 2] No such file or directory: '/home/builder/src/tmp-glibc/work-shared/target/kernel-source/tools/arch')

and the build failed horribly.

With this change it's an error which can not be missed:

ERROR: perf-1.0-r9 do_configure: Path does not exist: /home/builder/src/tmp-glibc/work-shared/target/kernel-source/tools/arch. Maybe PERF_SRC does not match the kernel version.
ERROR: perf-1.0-r9 do_configure: Function failed: copy_perf_source_from_kernel
ERROR: Logfile of failure stored in: /home/builder/src/tmp-glibc/work/target-linux/perf/1.0-r9/temp/log.do_configure.21083
NOTE: recipe perf-1.0-r9: task do_configure: Failed
ERROR: Task (/home/builder/src/poky/meta/recipes-kernel/perf/perf.bb:do_configure) failed with exit code '1'

To get get perf compiling from a custom kernel, a perf.bbappend can be
created which defines PERF_SRC as list of files and directories needed
from kernel source tree to compile perf. This varies between kernel
versions.
