Abhinav Aggarwal 0c36a942c9 Enable >= 2GiB file size support in backupToTar for 32 bit targets. ...

backupToTar function used in fullbackup currently uses off_t to
represent file sizes which overflows for files having size >= 2 GiB
on 32 bit target architectures.

This CL replaces off_t with off64_t to overcome this limitation.

Fixes: 157633626
Test: atest libandroidfw_tests
Test: Locally running a backup with a test app having a file of size
2GiB and verifying the size variable in backupToTar doesn't overflow
on a 32 bit target.
