EventService: Enhance inotify event filename handling

In kernel inotify, the inotify_event.name is padded to a mutiple of
sizeof(inotify_event) with '\0' and len is the size of char[] name,
not the actual size of name. So constructing the name string with
std::string(name, len) constructs a string with all the '\0's, which
is not equal to the filename. This patch uses std::string(name) so
that the string does not contain these '\0's.

Tested:
Manually create/delete /var/log/redfish, confirmed handler is entered
by log.
