OpenSSL::PKey::EC::Point missing `mul` method

[alextwoods]

It looks like the OpenSSL::PKey::EC::Point class is missing the mul method. It does look like bouncy castle's ECPoint class does support multiply.

Steps to reproduce

require 'openssl'
group = OpenSSL::PKey::EC::Group.new('prime256v1')
new_point = group.generator.mul(2)

Expected Result

# <OpenSSL::PKey::EC::Point>

In cRuby:

require 'openssl'
group = OpenSSL::PKey::EC::Group.new('prime256v1')
new_point = group.generator.mul(2) # returns <OpenSSL::PKey::EC::Point:0x000000010dc80218 @group=#<OpenSSL::PKey::EC::Group:0x000000010dc80268>>

Actual result

 undefined method `mul' for #<OpenSSL::PKey::EC::Point:0x1f39b3ba> (NoMethodError)

Version

• JRuby: 9.4.5.0
• jruby-openssl: jruby-openssl-0.14.6-java

Shouldn't be too hard to add with BC already implementing it.

Ok less easy since we are not using the BC ECPoint class in this impl. I'm trying to sort it out now.
