send-email: detect cycles in alias expansion

With the previous code, an alias cycle like:

  $ echo 'alias a b' >aliases
  $ echo 'alias b a' >aliases
  $ git config sendemail.aliasesfile aliases
  $ git config sendemail.aliasfiletype mutt

would put send-email into an infinite loop. This patch
detects the situation and complains to the user.
