Fix incorrect constant for O_LARGEFILE on mips64-linux-musl
Changes `O_LARGEFILE` from `0` to `0x2000`
Bash script used for ensuring constant is correct:
```sh
#!/bin/bash
echo "
#include <fcntl.h>
int largefile() {
return O_LARGEFILE;
}
" | mips64-linux-musl-gcc -c -O2 musl_o_largefile.c -o temp.o
mips64-linux-musl-objdump -d temp.o | grep -A2 largefile
```
Output:
```asm
0000000000000000 <largefile>:
0: 03e00008 jr ra
4: 24022000 li v0,8192 ; 0x2000
```
Link to relevant portion of kernel source, shows that it should match mips32 musl (which currently has a value of 0x2000 as well).
I believe the reason #2738 had this value incorrect was because it's 0 for glibc on mips64 (to specify it's the default, I believe).
