build: fix missing target_link_options for libraries

It seems that two targets `libOpenImageIO`, `libOpenImageIO_Util` were left out
during the [switch to target-based definitions]
(#4193)
refactor and have no `-ftest-coverage -fprofile-arcs` options added in
the CODECOV=1 mode.

This was due to #4193 failing to propagate the link options to the dynamic libraries.

Adding the missing options resolves build errors.
