Bugfix for extra extensions

Browse Source 
If extra extensions are provided to socksend_tls_clienthello(), the socksend_tls_clienthello() needs to determine what extensions were provided so that it doesn't add any of these extensions a second time. The code that was looping through the extra extensions to get the extension IDs was using the value for the length of the string. This commit fixes the error.
