perf tools: Fix build break on powerpc due to sample_reg_masks

The perf_regs.c file does not get built on Powerpc as CONFIG_PERF_REGS
is false.  So the weak definition for 'sample_regs_masks' doesn't get
picked up.

Adding perf_regs.o to util/Build unconditionally, exposes a redefinition
error for 'perf_reg_value()' function (due to the static inline version
in util/perf_regs.h). So use #ifdef HAVE_PERF_REGS_SUPPORT' around that
function.
