Create libi2c_dev_mock.a to solve linker errors
The i2c::create() function is currently defined in
mocked_i2c_interface.hpp. This causes linker errors if that header file
is included by multiple .cpp files in the same test executable.
Moved i2c::create() to mocked_i2c_interface.cpp so that it is only
defined once. Created the static library libi2c_dev_mock.a that
contains mocked_i2c_interface.o.
Test executables that need the mock version of i2c::create() should link
with libi2c_dev_mock.a.
Normal executables that need the real version of i2c::create() should
link with libi2c_dev.a as before. This has not changed.
