FreeTDM: gcc-4.6 fixes (-Wunused-but-set)

ftdm_io.c:
	Remove cut_path() function and call since it didn't seem to
	do anything useful anyway.

ftmod_analog.c/ftmod_analog_em.c:
	Remove status variable that was used for the result of codec_func(),
	but was never checked for errors or returned to the caller.

libteletone_generate.c:
	Remove unused variable "var".
