Author map correction and additions

[Joseph Myers]

Having reviewed entries in the author map for the git conversion that 
don't correspond directly to current /etc/passwd entries I think the 
following correction should be made:

alanm = Alan Matsuoka <alanm@redhat.com>
(not Alan Modra, at least for the commits I looked at)

In addition, at least the following ten committers who are new since the 
map was created need to be added:

afanfa = Alessandro Fanfarillo <fanfarillo.gcc@gmail.com>
afomin = Alexander Fomin <afomin.mailbox@gmail.com>
alahay01 = Alan Hayward <alan.hayward@arm.com>
andris = Andris Pavenis <andris.pavenis@iki.fi>
claziss = Claudiu Zissulescu <claziss@synopsys.com>
evandro = Evandro Menezes <e.menezes@samsung.com>
kelvin = Kelvin Nilsen <kdnilsen@linux.vnet.ibm.com>
lkrupp = Louis Krupp <louis.krupp@zoho.com>
ssaraswati = Sujoy Saraswati <sujoy.saraswati@hpe.com>
wilco = Wilco Dijkstra <wdijkstr@arm.com>
