I'm pretty sure that evf is the only format that the RTV_DOIT procedure outputs to disk. Your call to this procedure may not actually be correct, which maybe causing your evf file to not be generated correctly.

From your example:
ENVI_DOIT, 'RTV_DOIT', DIMS=dims, FID=fid, /IN_MEMORY, OUT_NAME=out_name, L_NAME=l_name, POS=0, VALUES=0

Only the value of zero in your raster will be converted to vector. The keywords in_memory, outname, l_name, pos & values all need to be arrays of the same length.

So for your case only the value of zero is wanted for conversion to vector:
pos =[0]
values=[0]
in_memory=lonarr(0)
out_name = ['test_zero_value.evf']
l_name = ['zero_class']

That is probably what you're after.

Cheers
Josh
