build runner: fix FTBFS on targets without `--watch` implementation
This was a regression in #24588.
I have verified that this patch works by confirming that with the
downstream patches SerenityOS apply to the Zig source tree (sans the one
working around this regression), I can build the build runner for
SerenityOS.
Resolves: #24682
