binary_writer.cpp: fix compatibility with boost-1.71.0

With newer boost 1.71.0 with:
boostorg/endian@6b57926#diff-5a08a00b5b1ec741b8b13cf3c1396874

boost/endian/conversion.hpp isn't included by
boost/endian/buffers.hpp and the build fails with:

src/anbox/common/binary_writer.cpp: In member function 'void anbox::common::BinaryWriter::write_uint16(uint16_t)':
