[libc++] Fix eager generator expression in DefineLinkerScript
As explained in https://gitlab.kitware.com/cmake/cmake/-/issues/21045,
both branches of an $<IF> generator expression are evaluated eagerly
by CMake. As a result, if the non-selected branch contains an invalid
generator expression (such as getting the OUTPUT_NAME property of a
non-existent target), a hard error will occur.
This failed builds using the cxxrt ABI library, which doesn't create
a CMake target currently.
