Fix #757 

I believe I discovered the reason for issue #757: f2303a0d79.

This commit removed attempted to replace `$cbc_cipher_list_hex` (which was computed on the fly) with `$cbc_ciphers_hex` (which is static). However, the function was still using `$cbc_cipher_list_hex`, and since it wasn't being initialized to "" at the beginning of the function, the second call to `run_beast()` (to handle the second IP address) just appended to the value created by the first. Then, when the first two bytes were removed from the resulting string the result was a malformed cipher suite list, which caused `tls_sockets()` to fail.
