scripts: Strip compiler suffixes in result scripts

Browse Source 
This can be explicitly disabled with -x/--no-strip in the relevant
scripts, but stripping by default seems to be more useful for composing
results in higher-level scripts. It's better for the result names to be
consistent, even if they don't match the .o symbols exactly.

Note some scripts are unaffected:

- cov.py - gcov doesn't seem to have an option for getting the
  unstripped symbols, so we only output the stripped names.

- structs.py - structs.py deals with struct names, which are notably not
  symbols.
