x/build: timeout on netbsd-arm64 builder

[dmitshur]

#!watchflakes
default <- builder ~ `netbsd-arm64` && (log ~ `SIGQUIT` || log ~ `test timed out` || `failed to start: context deadline exceeded`)

Filing this to hopefully catch future instances of issues like #73487, where the underlying problem was a timeout, but it was attributed to one of the many tests that were still executing at that time.

See #57847 for a previous similar issue from 2023.
