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.
