perf build: Remove PERF_HAVE_DWARF_REGS

PERF_HAVE_DWARF_REGS was true when an architecture had a dwarf-regs.c
file. There are no more architecture dwarf-regs.c files, selection is
done using constants from the ELF file rather than conditional
compilation. When removing PERF_HAVE_DWARF_REGS was the only variable
in the Makefile, remove the Makefile.

Add missing SPDX for RISC-V Makefile.

Need to use -fno-optimize-sibling-calls for test compilation,

and omitted from the stack unwind.

So far it was enabled only for x86.
