target-mips: fix mipsdsp_mul_q31_q31

Multiplication of two fractional word elements is not correct when sign
extension/promotion is needed. This change fixes it by adding correct
casts from unsigned to signed values.
In addition, the tests (dpaq_sa_l_w.c and dpsq_sa_l_w.c) have been extended
to trigger the current issue.
