CryptoPkg/OpensslLib: Exclude unnecessary files in process_files.pl

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1089

When running process_files.py to configure OpenSSL, we can exclude
some unnecessary files. This can reduce porting time, compiling
time and library size.

Upstream OpenSSL commit 71a5516dcc8a which was as part of
OpenSSL_1_1_1b, Add the STORE module(crypto/store/*).
But UEFI don't use them. So exclude these files.

Functions in crypto/rand/randfile.c OpenSSL and edk2 don't
call them. And it requires more crt runtime support.
So exclude it.
