Unroll the if-return/elif-return/else-return chain in test_cipher_on_target.

Rather than doing if-return, elif-return, else-return, just do
if-return, if-return, if-return. This provides no immediate benefit to
the code itself, but permits the introduction of code that alters the
$sigalg variable in between the first if-return and the latter two in an
upcoming commit.
