Go 1.23 tightens access to internal symbols, and even puts runc into "hall of shame" for using an internal symbol (recently added by commit da68c8e). So, while not impossible, it becomes harder to access those internal symbols, and it is a bad idea in general. Since Go 1.23 includes https://go.dev/cl/588076, we can clean the internal rlimit cache by setting the RLIMIT_NOFILE for ourselves, essentially disabling the rlimit cache. Once Go 1.22 is no longer supported, we will remove the go:linkname hack. (cherry picked from commit 584afc6) Signed-off-by: Kir Kolyshkin <[email protected]>

Since CL 588076 runc can do fine without the kludge. The code accessing the symbol is now guarded with `go:build !go1.23` in all supported runc branches (main: [1], release-1.1: [2]). This reverts part of CL 587219. Updates #67401. For #66797.
