posix: move checkexec test file to .hg/cache This avoids unnecessary churn in the working directory. It is not necessarily a fully valid assumption that .hg/cache is on the same filesystem as the working directory, but I think it is an acceptable approximation. It could also be the case that different parts of the working directory is on different mount points so checking in the root folder could also be wrong.
