perf tools: Fix perf regs mask generation

On some architectures (powerpc in particular), the number of registers
exceeds what can be represented in an integer bitmask. Ensure we
generate the proper bitmask on such platforms.

Fixes: 71ad0f5e4 ("perf tools: Support for DWARF CFI unwinding on post processing")
