bitcode support for libcrypto.a, libssl.a

Found Issue

• Related Issue - https://github.com/krzyzanowskim/OpenSSL/issues/78
• openssl binary files(libcrypto.a, libssl.a) don't have bitcode identifiers inside its binary. You cannot find any bitcode keywords, though you run below command.

$ otool -l libcrypto.a | grep __bitcode

# You can find bitcode keyword, if binary has bitcode.
# sectname __bitcode
# sectname __bitcode
# sectname __bitcode

How to Fix and What This PR do

• In build.sh configure() function does not embed CFlag -fembed-bitcode.
• This PR adds -fembed-bitcode flag and updates openssl binary.

Information of updated Binary File

• Binary files for iOS gets 3 times bigger than previous files.
• I also thought it was strange that the size of the two was very different. However, I also tried building the openssl binary with OpenSSL for iPhone. And the results were not very different.

file name	current state	embed bitcode
libcrypto.a	15.1MB	45.2MB
libssl.a	2.6MB	8.5MB

thanks. Would you mind to keep only script changes here? I'm unlikely to accept binary update in PR
