fft: remove gst_init() for g-i scanner again

libgstfft doesn't actually use any symbols from libgstreamer, so when
compiling with -Wl,--as-needed it won't even link to it, which can
cause failures with older versions of g-i that ignore the --pkg
arguments.

Should fix PPA build failure on Ubuntu Maverick
