[PATCH] perf tools: fix build breakage on arm and arm64 targets

[Will Deacon]

Attempting to build the perf tool on arm or arm64 targets results in the
following failure:

arch/arm/util/unwind-libunwind.c: In function ‘libunwind__arch_reg_id’:
arch/arm/util/unwind-libunwind.c:43:3: error: implicit declaration of function ‘pr_err’ [-Werror=implicit-function-declaration]
   pr_err("unwind: invalid reg id %d\n", regnum);
   ^
This is due to commit 84f5d36f4866 ("perf tools: Move pr_* debug macros
into debug object") moving the pr_* macros into a new header file, but
failing to update architectures other than x86.

This patch adds the missing includes, and fixes the build again.
