perf probe: Cleanup debuginfo related code
Cleanup debuginfo related code to eliminate fragile code which
pointed by Ingo (Thanks!).
1) Invert logic of NO_DWARF_SUPPORT to DWARF_SUPPORT.
2) For removing assymetric/local variable ifdefs, introduce
more helper functions.
3) Change options order to reduce the number of ifdefs.
