Subject: Rename git-init-shared(1) to git-init-acl(1)

We have always felt that the name of this program was too close to the
invocation of 'git init --shared' which does something similar. Make it
clear in the name that we're working with POSIX ACLs instead of normal
permission sets as 'git init --shared' does.
