build: rename event.h to gf-event.h

Newer FreeBSD versions (noticed with 10.3-RELEASE) provide a event.h
file that on occasion gets included instead of the libglusterfs file.
When this happens, 'struct event_pool' will not be defined and building
will fail with errors like:

    autoscale-threads.c:18:55: error: incomplete definition of type 'struct event_pool'
            int                      thread_count   = pool->eventthreadcount;
                                                      ~~~~^
    autoscale-threads.c:17:16: note: forward declaration of 'struct event_pool'
            struct event_pool       *pool           = ctx->event_pool;
                   ^

This problem is caused by 'pkg-config --cflags uuid' that adds
/usr/local/include to the GF_CPPFLAGS. The use of libuuid is preferred
so that the contrib/uuid/ directory can be removed.

By renaming event.h to gf-event.h there is no conflict between the
different event.h files anymore and compiling on FreeBSD works without
issues.
