alias rule does not copy usage-requirements

Hello,

I've just come across an alias rule limitation -- it does not copy
usage-requirements. For example, suppose I have thirdparty library
declaring two libs -- util and main. main has a usage-requirement
<library>util. Now if I will declare an alias for main it will not
copy usage-requirement, hence it will not work as an alias.

Not sure what is the right way to fix it, since not all targets have
usage-requirements...
