[PATCH 15/17] perf tests task_analyzer: fix bad substitution ${$1}

[Athira Rajeev <atrajeev@linux.vnet.ibm.com>]

From: Aditya Gupta <adityag@linux.ibm.com>

${$1} gives bad substitution error on sh, bash, and zsh. This seems like
a typo, and this patch modifies it to $1, since that is what it's usage
looks like from wherever `check_exec_0` is called.

This issue due to ${$1} caused all function calls to give error in
`find_str_or_fail` line, and so no test runs completely. But
'perf test "perf script task-analyzer tests"' wrongly reports
that tests passed with the status OK, which is wrong considering
the tests didn't even run completely
