MIPS: Fix RLIM64_INFINITY constant for O32 and N32 ABIs
Fix the RLIM64_INFINITY constant for O32 and N32 ABIs to match the kernel one. Change the getrlimit64/setrlimit64 into old compat symbols, and provide the Linux generic getrlimit64/setrlimit64 functions as GLIBC_2_19 version.

* sysdeps/unix/sysv/linux/mips/getrlimit64.c: On O32 and N32 ABIs,
include the generic getrlimit64 version as __internal_getrlimit64
and add a wrapper around it to convert the RLIM64_INFINITY constant
