Factor out a new function from ApplyFromSdcard that installs a package from a local path. Inside this function, we start the fuse and choose the type of data provider depending on the path string. And similar to the existing logic, we treat the package as a block map if the path starts with a '@'. This is part of the effort to install larger than 2GiB packages on ILP32 devices. Bug: 127071893 Test: Build a 32 bit sailfish and create a 3GiB OTA package. Sideload the package, uncrypt and install the package from sdcard. Change-Id: I328ea34fa530731acbce7554bfc3059313ad6ece
