flashrom.c: Implement file-based locking semantics
This upstreams the ChromiumOS implementation of file-based locking for multiple instances of flashrom that could be spawned either from libflashrom (perhaps by fwupd for example) and user cli as another example. Since flashrom is programming singleton state of hardware from userspace there is no way to exclusively own the address space and therefore a file-based locking semantic is considered here.
