Fix aml dependency version for neatvnc

Building neatvnc v0.8.1 fails with:
```
meson.build:71:7: ERROR: Dependency "aml" not found, tried pkgconfig and
cmake
```
According to meson.build:66, neatvnc requires aml in the range
`>=0.3.0` and `<0.4.0`.

Update the dependency to match this requirement so the build can
succeed with the proper aml version.
