play: Avoid gcc warning when compiling without readline.

The EXPORT_PLAY_CMD_HANDLER() macro is only used when READLINE support
is enabled, which leads to

	play.c:112: warning: macro "EXPORT_PLAY_CMD_HANDLER" is not used [-Wunused-macros]

Define the macro only when HAVE_READLINE is defined by moving down
the definition to the first user, com_quit().
