mailmap: use higher level string list functions 

No functional changes intended. This commit makes use of higher level
and better documented functions of the string list API, so the code is
more understandable.

Note that also the required computational amount should not change
in principal as we need to look up the item no matter if it is already
part of the list or not. Once looked up, insertion comes for free.
