net/http/pprof: skip TestDeltaProfile on all arm and arm64 architectures

Given that we have seen failures with the same failure mode on both
openbsd/arm and android/arm64, it seems likely that the underlying bug
affects at least all ARM-based architectures.

It appears that either these architectures are not able to sample at
the frequency expected by the test, or the samples are for some reason
being dropped.

For #50218
