[PATCH] devtools: fix mailmap check for parentheses

[Thomas Monjalon]

When checking names having parentheses, the grep matching was failing.
It is fixed by escaping the open parenthesis.

Also, the mailmap path was relative to the root directory.
The path is made absolute.

Fixes: e83d41f0694d ("mailmap: add list of contributors")
Fixes: 83812de4f2f3 ("devtools: move mailmap check after patch applied")
