perf tests: Fix test_arm_callgraph_fp variable expansion

Browse Source 
[ Upstream commit 33fe7c0844 ]

$TEST_PROGRAM is a command with spaces so it's supposed to be word
split. The referenced fix to fix the shellcheck warnings incorrectly
quoted this string so unquote it to fix the test.

At the same time silence the shellcheck warning for that line and fix
two more shellcheck errors at the end of the script.

Fixes: 1bb17b4c6c ("perf tests arm_callgraph_fp: Address shellcheck warnings about signal names and adding double quotes for expression")
