perf test shell: Prevent temporary editor files from being considered test scripts

Allows a perf shell test developer to concurrently edit and run their
test scripts, avoiding perf test attempts to execute their editor
temporary files, such as seen here:

 $ sudo taskset -c 0 ./perf test -vvvvvvvv -F 63
 63: 0VIM 8.0                                              :
 --- start ---
 sh: 1: ./tests/shell/.record+probe_libc_inet_pton.sh.swp: Permission denied
 ---- end ----
 0VIM 8.0: FAILED!
