libcacard: s/strip(args++)/strip(args+1)

vcard_emul_options used args = strip(args++) a few times, which
was not returning the expected result since the rest of the code
expected args to be increased by at least 1, which is not the case
if *args is not a blank space when this function is called.
Replace these calls by "strip(args+1)" which will do what we expect.
