Fix option individual_zyg

[dglemos]

Issue reported here: https://github.com/Ensembl/ensembl-vep/issues/1703

The option individual_zyg uses the following variables:

• $vf->{hom_ref}->{$ind} = 1
• $vf->{non_variant}->{$ind} = 1

However, these variables are used in other parts of the code as: vf->{hom_ref} = 1 $vf->{non_variant} = 1

The solution is to rename the variables.

Testing Input:

CHROM POS ID REF ALT QUAL FILTER INFO FORMAT ind

chr1 115258730 . C . . . . GT 0/0

Fixed. Thanks, @nakib103!
