[PATCH 02/12] t4216: use an '&&'-chain

In a759bfa9ee (t4216: add end to end tests for git log with Bloom
filters, 2020-04-06), a 'rm' invocation was added without a
corresponding '&&' chain.

When 'trace.perf' already exists, everything works fine. However, the
function can be executed without 'trace.perf' on disk (eg., when the
subset of tests run is altered with '--run'), and so the bare 'rm'
complains about a missing file.

To remove some noise from the test log, invoke 'rm' with '-f', at which
point it is sensible to place the 'rm -f' in an '&&'-chain, which is
both (1) our usual style, and (2) avoids a broken chain in the future if
more commands are added at the beginning of the function.
