fix: Potential EEXIST error when iOS asset catalog dir already exists

[robhogan]

Summary:

#1971 sought to replace fs-extra with native fs APIs but missed the behaviour difference of the subtly-differently-named API. fsExtra.mkdirsSync operates like mkdir -p - recursively creating non-existent directories, and not complaining when a directory already exists.

This is the behaviour of fs.mkdirSync if and only if recursive is set.

If recursive is false and the directory exists, an EEXIST error occurs.
