fix: Fix sporadic test.profiling failures (#1056)

Using cut, which is always line-based, to remove bytes from a binary file can
cause problems if the binary timestamp field happens to contain a newline
character, which causes test.profiling to fail <1% of the time. Instead use tail
which has a character mode that ignores newlines.
