Fix choosing wrong diff tool for recovery-from-boot patch

'bsdiff' tool should be used when recovery and boot image
have mismatching entries. This includes not only the case
when system_as_root enabled, but include_recovery_dtbo and
include_recovery_acpio too.

Add check if they are enabled to synchronize logic with
core/Makefile, which already takes this into account.

Test: make dist -j
