As discovered in https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/.60ui.60.20tests.20re-running.3F the linker script added in #121967 can trigger rebuilds or new test executions, as it's more recent than some of the existing files themselves.
This PR copies the mtime to the linker script to prevent a second invocation of
./x test tests/ui
from rerunning all of the tests.
