rs6000: Properly handle LE index munging in vec_shr (PR94710)

The PR shows the compiler crashing with -mvsx -mlittle -O0.  This turns
out to be caused by a failure to make of the higher bits in an index
endian conversion.

* config/rs6000/vector.md (vec_shr_<mode> for VEC_L): Correct little
endian byteshift_val calculation.
