mail/fetchmail: update to 6.4.34 (critical fix)

= CRITICAL BUG FIXES:
* When an SMTP receiver refuses delivery, a message would be deleted from
  the mail store in spite of a softbounce option that is enabled.
  Bug report, analysis and patch by Horváth Zsolt. Gitlab, fixes #50.

= BUILD NOTE:
* If you are reusing config.cache from prior builds, this may cause
  issues with finding Python or some libraries.  In case of trouble,
  remove config.cache and retry.
