Subject: lib/wasm: provide fs.constants.O_DIRECTORY definition
X-Git-Tag: go1.24rc1~3^2~18

lib/wasm: provide fs.constants.O_DIRECTORY definition

CL 606658 added a constants.Get("O_DIRECTORY").Int() call at init time,
which panics in browsers because O_DIRECTORY is undefined. It needs to
be a JavaScript number to avoid that.

Fixes #70723.
