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.
