perf build: Specify shellcheck should use bash

Browse source 
When someone has a global shellcheckrc file, for example at
~/.config/shellcheckrc, with the directive 'shell=sh', building perf
will fail with many shellcheck errors like:

    In tests/shell/base_probe/test_adding_kernel.sh line 294:
    (( TEST_RESULT += $? ))
    ^---------------------^ SC3006 (warning): In POSIX sh, standalone ((..)) is undefined.

    For more information:
      https://www.shellcheck.net/wiki/SC3006 -- In POSIX sh, standalone ((..)) is...
    make[5]: *** [tests/Build:91: tests/shell/base_probe/test_adding_kernel.sh.shellcheck_log] Error 1

Passing the '-s bash' option ensures that it runs correctly regardless
of a developers global configuration.

This patch adds '-s bash' and other options to the SHELLCHECK variable
in Makefile.perf and makes use of the variable consistently.
