blktap2: fix vhd compilation under uclibc

blktap2 was not compiled succesfully under uclibc, with the following
error:

gcc     -o vhd-util vhd-util.o -Llib -lvhd
lib/libvhd.so: undefined reference to `libiconv_open'
lib/libvhd.so: undefined reference to `libiconv_close'
lib/libvhd.so: undefined reference to `libiconv'

This patchs add the flag -liconv when blktap2/vhd is compiled on
uclibc.
