get_maintainer: emit longer section headers

Section headers can be quite long and some are very long and duplicated
for many initial characters.

The current maximum length emitted for a section header is 20 bytes (or
17 bytes then ...  when the section header length is > 20).

Change that length to 50 so more of the section is shown.

Example new output:
$ ./scripts/get_maintainer.pl -f drivers/net/ethernet/broadcom/bnx2x/

Old:
$ ./scripts/get_maintainer.pl -f drivers/net/ethernet/broadcom/bnx2x/
