Four tests in lib/std/posix/test.zig were disabled because they created fixed-name files in the current working directory, and this caused problems if tests were running in parallel with other build's tests. This PR fixes those tests to all use `std.testing.tmpDir` to create unique temporary names and directories. Also clean the tests up to more consistently use `defer` to clean up, or to just rely on tmpDir cleanup to remove individual files. Working on these tests revealed a bunch of stale WASI code paths in posix.zig, fixed by replacing stale `wast.AT.FDCWD` references with just `AT.FDCWD`. Fixes ziglang#14968.

Seems reasonable to me, but will let @squeek502 check the WASI bits and merge. |
