These 2 patches improve the efficiency and quality of the
lib/coresight.sh script.

The first one uses grep's `-c` parameter to count the results instead of
piping it to `wc -l`.
The second one replaces the use of backticks (`...`) with $(...) as the
former has several potential issues while the latter does not.

Diederik de Haas (2):
  perf test: Replace 'grep | wc -l' with 'grep -c'
  perf test: Replace legacy `...` with $(...)
