chore(adhoc): if not spyName is available, use 'unknown'

[eh-am]

As implemented in #1300
Only a certain list of spyNames are allowed (https://github.com/pyroscope-io/pyroscope/pull/1300/files#diff-4470a525fa07e3755143aea910fec818e7ad9dc18fd97f5f60203a7f43b73e79R3-R19)

In adhoc we were by default in pprof/collapsed to use the appName as the spyName.
With this PR we use unknown instead.
