prlimit: add name redirection and fix incorrect parameters to syscall
The tst-rlimit/tst-rlimit64 tests pointed to several issueses in
prlimit() function for 32-bit CPUs. This patch adds name redirection to
prlimit64 in prlimit declaration to provide correct support for 64-bit
offset (_FILE_OFFSET_BITS=64) on 32-bit CPUs and fixes improper field
assignment and incorrect syscall paramerets in the prlimit() function.
Fixes: 8c2f6218 ("setrlimit/getrlimit: fix prlimit64 syscall use for 32-bit CPUs")
