MAINTAINERS: Fix format for file entries (F:)

According to the documentation further up in the file:

F:   drivers/net/    all files in and below drivers/net
F:   drivers/net/*   all files in drivers/net, but not below
F:   */net/*         all files in "any top level directory"/net

Add trailing slashes to directory names.
