Punch extracted ELF64 files

Punch holes in extracted elf files in same manner as apks and embedded
shared libs. fallocate may not work on file systems which  don't allow
punching compressed files like f2fs. But that shouldn't hamper any
functionality.

Test: acloud delete --all && m && acloud create --local-instance --local-image && adb logcat -c && m FileSystemUtilsTests && atest -c FileSystemUtilsTests
