openssl: Upgrade 1.0.2k -> 1.0.2l

openssl: Upgrade 1.0.2k -> 1.0.2l

1. Dropped obsolete patches, because the new version contains them:
  - fix-cipher-des-ede3-cfb1.patch
  - openssl-avoid-NULL-pointer-dereference-in-EVP_DigestInit_ex.patch
2. LICENSE checksum change due to copyright years and wording tweak.
3. Test binaries (x86-64) are included in source code. So remove those
only for ptest.
