Bug 1808416 - Do not check crashreporter symbols on tsan r=jmaher

In mozharness, setting --download-symbols=True or --download-symbols=ondemand
triggers an attempt to access the symbols url (either to download them or just
verify that they exist). asan and tsan builds only have the special "full"
symbols, which are never used by mozharness. Removing the --download-symbols
option from the command line avoids the url check entirely, which avoids
retries, warnings, and errors in the log.
