syscall: fix Fchdir on js/wasm
NodeJS does not support fchdir so it has to be emulated with chdir by
saving the path when opening a directory.
However, if the path opened is relative, saving this path is not
sufficient, because after changing the working directory the path
does not resolve correctly any more, thus a subsequent fd.Chdir() fails.
This change fixes the issue by resolving a relative path when
opening the directory and saving the absolute path instead.
Fixes #37448
