Add tilde expansion to build-settings.ts resolvePathFromCwd

The duplicate resolvePathFromCwd in build-settings.ts was missing
tilde expansion. This caused derivedDataPath with ~ to work during
builds but fail when resolving app paths from build settings (used
by build_run_device and get_device_app_path).
