email plugin: Make UNIX socket path configurable at compile time.

The prefix for the UNIX socket can be configured using the
COLLECTD_SOCKET_PREFIX macro. "email" will be prepended to it.

If you configure collectd using

  CFLAGS="-DCOLLECTD_SOCKET_PREFIX='\"$path-\"'" ./configure

the socket will be found at "$path-email".
