target/arm: Use dup_const() instead of bitfield_replicate() 

Use dup_const() instead of bitfield_replicate() in
disas_simd_mod_imm().

(We can't replace the other use of bitfield_replicate() in this file,
in logic_imm_decode_wmask(), because that location needs to handle 2
and 4 bit elements, which dup_const() cannot.)
