[PATCH 11/17] perf/tests/shell: fix shellscript errors for lock_contention.sh

Wed Jun 14 02:41:39 AEST 2023
From: Abhirup Deb <abhirupdeb at linux.vnet.ibm.com>
Use quotes around variables to prevent POSIX word expansion,
use uppercase for signals(INT, TERM, EXIT) to avoid mixed/lower case
naming of signals and replace "==" with "=" as "==" is not
supported by POSIX shell.
