java: update source and target version to 17
Fixes the obsolete version warning when building.
What changed, and why it matters
This commit simply changes the Java compiler target version from 1.8 to 17 in the build configuration. It is a routine build hygiene change to silence an obsolete-version warning and does not alter any program logic, cryptographic code, or security behavior.
No security action required. Review downstream build compatibility if Java 17 runtime support is not already guaranteed.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The single-line change in configure.ac sets JAVAC_TARGET=17 instead of 1.8. This affects only the Java bytecode version produced when building libwally-core’s Java bindings. It is not a security patch and introduces no code changes.
