RFR: 7512: Update lz4-java and remove the osgi bundle name override

[Brice Dutheil]

The core library dependency decalred in maven is aligned with the one in the .target files, `1.8.0`.

Also I noticed the lz4-java library has an OSGI bundle symbolic name: `lz4-java`, introduced in 1.3.0 : https://github.com/lz4/lz4-java/pull/39/files#diff-e3399fe1dc27b086e517883c6cab943edbfab64139839c965b14db8d11c8a99aR1-R4
However probably due to some previous bugs this required an override, done [here](https://github.com/openjdk/jmc/commit/b6e5bde2f45e7e44f252f42488332fc81b58506b#diff-ae8e739504eac3280387ceb987f669e68fbb07806266732c4ab21409d593b1dcR81-R86), but this may not be necessary anymore. Hence this PR tries to use the actual osgi name.

The change is little, and hopefully won't ripple beyond.
