perf tests test_arm_spe: Address shellcheck warnings about signal name case

Running shellcheck -S on test_arm_spe.sh throws below warnings:

 #shellcheck -S warning tests/shell/test_arm_spe.sh
In tests/shell/test_arm_spe.sh line 30:
trap cleanup_files exit term int
                   ^--^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined.
                        ^--^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined.
                             ^-^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined.

Fixed this issue by using uppercase for "EXIT", "TERM" and
"INIT" signals to avoid using lower/mixed case for signal
names as input.
