Update JNI Target relocation record to have offset to the reloLocation.

[dsouzai]

Reverts¹ #6330 which was a revert of #6326

On x86, the JNI Target relocation puts the incorrect address when
generating a Runtime Assumption. However, the address that the
relocation infra itself needs to patch is correct. Thus, the relo record
has to hold not just the location to patch but also the location to
register the assumption against. This is the same on most platforms, but
different on x86.

eclipse-openj9/openj9#14421 depends on this change; OpenJ9 will be broken without a coordinated merge.

1. Note: because of the force push, this is no longer technically a revert. However, the force push only updated copyrights in a comment block, and so there is no functional difference between this PR and Update JNI Target relocation record to have offset to the reloLocation. #6326.

LGTM once both files' copyright dates are updated

[dsouzai]

Copyrights updated in force push.

@mstoodle, I diffed the diffs and these are exactly the changes that you already approved in #6326, except that the copyright dates are also updated

[mstoodle]

Still looks fine (even better with the updated copyrights...good catch!).

Gonna have to open yet another PR; because I force pushed, it's causing OpenJ9 OMR mirroring to fail.
