perf auxtrace: Fix multiple use of --itrace option
If the --itrace option is used more than once, the options are
combined, but "i" and "y" (sub-)options can be corrupted because
itrace_do_parse_synth_opts() incorrectly overwrites the period type and
period with default values.
For example, with:
--itrace=i0ns --itrace=e
The processing of "--itrace=e", resets the "i" period from 0 nanoseconds
to the default 100 microseconds.
Fix by performing the default setting of period type and period only if
"i" or "y" are present in the currently processed --itrace value.
