git-notify: Optionally call mail(1) without "-a"

Not all mail(1) implementations support specifying additional header
fields via "-a": with some, this flag is used for attaching files,
others don't provide an "-a" flag at all (this is true for the /bin/mail
utility currently installed on the SourceForge servers, for example).
We now provide the "-H" flag and the "notify.legacyMail" configuration
key for these cases.
