[OE-core] [PATCH 6/6] perf: fix undefined pr_* routines

[Bruce Ashfield]

When cross compiling libunwind support for ARM a missing debug include means
that pr* macros are not expanded, and hence link failures on the undefined
functions.

Since we must be compatible with many versions of the kernel and perf, we
sed the proper include into the files, while the permanent fix goes upstream
to the mainline kernel.
