Fix build on systems with glibc >= 2.30 (#28012)
On newer systems with glibc 2.30, the compiler emits a warning: In file included from coreclr/src/pal/src/misc/sysinfo.cpp:32: /usr/include/sys/sysctl.h:21:2: error: "The <sys/sysctl.h> header is deprecated and will be removed." [-Werror,-W#warnings] #warning "The <sys/sysctl.h> header is deprecated and will be removed." ^ The glibc 2.30 release notes cover this at https://sourceware.org/ml/libc-alpha/2019-08/msg00029.html: * The Linux-specific <sys/sysctl.h> header and the sysctl function have been deprecated and will be removed from a future version of glibc. Application should directly access /proc instead. For obtaining random bits, the getentropy function can be used. To keep coreclr release/3.1 building, disable treating the #warning as an error. Clang and GCC have separate flags to turn this error off.
