The k/uprobe_sytax_errors test case defines a check_error() function
used to run a command and check the position of the caret in the
output.
This would be useful for other ftrace facilities too, so move it to
test.d/functions for use by anyone. In the process, rename it to
ftrace_errlog_check() and parametrize it for general use.

Add error_log testcase for error logs on probe events.
This tests most of error cases and checks the error position
is correct.
