Deflake exec test.
- Only use MAXSYMLINKS/2+1 symlinks for each of the interpreter and script
paths in SymlinkLimitRefreshedForInterpreter to tolerate cases where the
original paths (/tmp, /bin, or /bin/echo) themselves contain symlinks.
- Ensure that UnshareFiles performs execve immediately after clone(CLONE_VFORK)
(no heap allocation for ExecveArray/RunfilesPath).
- Use lstat() rather than stat() for the existence check in fs_util's Exists;
the latter will fail if the symlink target does not exist, even if the
symlink does.
