mips: Fix argument passing for inlined syscalls on Linux [BZ #25523]
According to [gcc documentation][1], temporary variables must be used for the desired content to not be call-clobbered. Fix the Linux inline syscall templates by adding temporary variables, much like what x86 did before (commit 381a0c26d73e0f074c962e0ab53b99a6c327066d). Tested with gcc 9.2.0, both cross-compiled and natively on Loongson 3A4000. [1]: https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html
