ziparchive: Allow ExtractEntryToFile() to work with block device.
FileWriter::Create() calls ftruncate(2) to truncate the destination
file, which doesn't work with FD that references a block device. It
leads to kIoError when calling ExtractEntryToFile() to extract an entry
to block device FD.
As a result, it fails the package_extract_file() command in OTA updates
(e.g. 'package_extract_file("boot.img",
"/dev/block/platform/soc.0/f9824900.sdhci/by-name/boot")').
This CL skips the call to ftruncate(2) if FD references a block device.
Bug: 32903624
Test: ziparchive-tests works.
Test: Build an OTA updater (m updater) and call package_extract_file().
