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.
