ANDROID: fix up sysctl_vals change in 5.15.58

In commit 78e36f3b ("sysctl: move some boundary constants from
sysctl.c to sysctl_vals"), the sysctl_vals[] array changed size and
contents, which does not work well when external modules are accessing
it and relying on it to have the same contents.

Fix this up by putting back the original values and size and creating a
new array, sysctl_vals_new, that is used by the #define values in
include/linux/sysctl.h.  If any existing module that used sysctl_vals is
rebuilt, it will then require sysctl_vals_new to be exported (as it
pickes it up from the #define), so add the symbol to the exported symbol
list to ensure that existing code all still builds and works properly.
