e521861508 Create a fallback to install from fuse if mmap fails
We may fail to memory map the package on 32 bit builds for packages with
2GiB+ size. This cl tries to install the package with fuse when memory map
fails in such cases.

Bug: 127071893
Test: build 32 bit version sailfish, push package and block.map, reboot into recovery with
the corresponding update_package argument.

f6158eb918 Support starting fuse from a block map
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.
