Improve support for FUSE_NOTIFY_INVAL_ENTRY notifications and trigger Finder refresh.

A FUSE_NOTIFY_INVAL_ENTRY notification is fired to inform the kernel that the specified file has a new identity, possibly due to having been renamed remotely. As a result, the vnode is removed from the name cache, a VNODE_EVENT_RENAME event is fired and the vnode’s identity is updated on its next lookup.

For details, see macfuse/macfuse#960 and macfuse/macfuse#470.
Improve fault tolerance when looking up vnodes.

In case a vnode type change is detected during a VNOP_LOOKUP call, the original (now outdated) vnode is revoked and a new node is created automatically without returning an error. The error condition will be logged.

For details, see macfuse/macfuse#894.
Optimize build script
- Reset build environment before running target actions. This reduces the number of unnecessary target rebuilds.
- Remove obsolete build cache index before creating new index under the same name.
