Add Terminal's native fragment for Linux riscv64 (#1210)

- add a new fragment 'org.eclipse.cdt.core.linux.riscv64' containing
compiled riscv64 natives suitable for the Linux riscv64
platform.

- add the 'libserial.so' binary compiled for
Linux riscv64, for the serial communication interface.

- add the linux/gtk/riscv64 environment triplet to various Maven
build scripts to support building CDT software for that environment.

Fixes #980
