8370493: [ubsan] aotMapLogger.cpp:864:44: runtime error: applying non-zero offset NNNNN to null pointer

[matias9927]

The UBSAN tool found undefined behavior in the aotMapLogger which relates to JDK-8366062. This patch applies an updated fix for both issues that places address + offset calculations in archiveUtils with proper casting to avoid the UBSAN error. Verified with tier 1-5 tests.
