FortranCInterface: Honor CMAKE_EXE_LINKER_FLAGS under CMP0056
Policy CMP0056 determines whether `CMAKE_EXE_LINKER_FLAGS` are passed
into the test project used by the source-file signature of `try_compile`.
That affects how implicit link directories are detected, so we need to
also honor the policy for the source-directory signature of `try_compile`
used in FortranCInterface in order to get matching link directories.
Fixes: #21408
