[dpdk-ci] [PATCH v3 02/10] tools: match by tree URL instead of tree name

The tree URL has more information. It can be used to
get the maintainer of a tree, and it includes the tree name anyway.
Although we can construct the tree URL by prepending
"git://dpdk.org/next/" to the trees that have "next-" in their name,
and prepending "git://dpdk.org/" to anything else, it would be safer
to read the URL from the MAINTAINERS file just in case new trees that
don't follow this rule were added.

Also try to use named capture groups as much as possible.
