This makes it possible to build and test mold in a path that contains whitespace characters - with the notable exception of the tests where `LD_PRELOAD` is used. That's because `LD_PRELOAD` unconditionally treats any whitespace as separator, regardless of quoting. The following ShellCheck warnings are eliminated by this commit: * SC2046: Quote this to prevent word splitting. * SC2086: Double quote to prevent globbing and word splitting.
