deps: update openssl.gyp/gypi for openssl-1.0.2a

Update gyp sources for openssl-1.0.2a. The source list was extracted
from Makefiles in `deps/openssl/openssl/{crypto/ssl/engines}`.

Defines are created by referring the table in
`deps/openssl/doc/openssl_define_list.pdf` that was derived from
Makefile entries and outputs of
`deps/openssl/openssl/Configure TABLE`.

Renamed the variable of openssl_sources_arm_elf_gas to
openssl_sources_arm_void_gas to be consistent with PERLASM_SCHEME.

This also includes arm64 support.
