The kernel does does contain that file.  In CentOS linux 7 (and 8), the
file is actually blank .. well is has one comment line:

# Placeholder file, no vDSO hwcap entries used in this kernel.

If you want the error to go away, just as the root user, do:

touch /etc/ld.so.conf.d/kernel-3.10.0-1127.19.1.el7.x86_64.conf
chmod 444 /etc/ld.so.conf.d/kernel-3.10.0-1127.19.1.el7.x86_64.conf

The above 2 commands should create a zero size file there and prevent
the error.

As to how you got the error .. it seems there is an issue with the
kernel-3.10.0-1127.19.1.el7.x86_64 install on your machine, it is at
least missing that file.  If you are using that kernel .. you might want
to re-install it instead to make sure all the files are there.  There is
a newer kernel released for EL7.

As to the purpose of /etc/ld.so.conf.d/, info here:
