openssl_1.0.2n: improve reproducibility

Improve reproducible build of:

openssl-staticdev
openssl-dbg
libcrypto

There are two main causes that prevent reproducible build, both related to
the generated file "buildinf.h":

1. "buildinf.h" contains build host CFLAGS, containing various build
   host references.  We need to pass sanitized CFLAGS to the script
   generating this file ("mkbuildinf.pl". )

2. We also need to modify the script "mkbuildinf.pl" itsel in order to
   generate a build timestamp based on SOURCE_DATE_EPOCH, if present in
   the environment.
