MIPS: asm: elf: Set O32 default FPU flags

Set good default FPU flags (FR0) for O32 binaries similar to what the
kernel does for the N64/N32 ones. This also fixes a regression
introduced in commit 46490b572544 ("MIPS: kernel: elf: Improve the
overall ABI and FPU mode checks") when MIPS_O32_FP64_SUPPORT is
disabled. In that case, the mips_set_personality_fp() did not set the
FPU mode at all because it assumed that the FPU mode was already set
properly. That led to O32 userland problems.
