[build] Use local .deps directory for users (fix #4998)

For an user setup we'd prefer to download Skia inside a .deps
directory (just to simplify the setup). For developers it's better if
we offer a common/shared/absolute directory so different local
Aseprite clones can share the same downloaded Skia version.
