linux-user: correct argument number for sys_mremap and sys_splice

sys_mremap missed 5th argument (new_address), which caused examples that
remap to a specific address to fail.
sys_splice missed 5th and 6th argument which caused different examples to
fail.
This change has an effect on MIPS target only.
