It will embed the full path of the library.  The problem is, it might
embed multiple variants of the same library in the same binary.

For the libcairo problem, see <https://issues.guix.gnu.org/47115#22>.
Turns out it wasn't a segfault but another kind of problem.
And it wasn't due to deduplication but rather buggy grafting.
Still, I suppose something similar can happen with propagation.
