perf dwarf: Avoid redefinition warnings for REG_DWARFNUM_NAME

Browse source 
dwarf-regs.c includes an arch-specific dwarf-regs-table.h for several
architectures. This pulls in different definitions of REG_DWARFNUM_NAME
and causes compiler warnings for W=1 builds.

In file included from util/dwarf-regs.c:23:

  .../dwarf-regs-table.h:5: error: "REG_DWARFNUM_NAME" redefined [-Werror]
   #define REG_DWARFNUM_NAME(reg, idx) [idx] = reg

Undefine REG_DWARFNUM_NAME before each new definition.
