msmtp: Update to 1.8.7

Changes:
1.8.7
-----
- Extend `from' command that sets the envelope from address: the
  patterns %U, %H, %C, %M are now replaced with user name, host name,
  canonicalized host name, and the contents of /etc/mailname. This is
  useful for system-wide installations and is more powerful than the old
  auto_from and maildomain commands, which are now deprecated (but still
  supported, of course).

1.8.6
-----
- Aliases are now expanded recursively
- Minor bug fixes
