libavb: replace CRC32 implementation

Replaces the CRC32 implementation with a version that uses the Android
license and optimizes for space rather than speed.

We're only using CRC32 for a 28-byte buffer so efficiency doesn't
matter much, but the cost of a 1KiB lookup table can be significant in
space-constrained bootloaders.

Bug: 170111993
Test: libavb_host_unittest
