Tests: Add two RISC-V Filter test files.

These test files achieve 100% code coverage in
src/liblzma/simple/riscv.c. They contain all of the instructions that
should be filtered and a few cases that should not.

+    good-1-riscv-lzma2-1.xz uses the RISC-V filter and LZMA2. The
+    uncompressed data is constructed so it tests all of the instructions
+    that should be encoded and a few that should not. Additionally, the
+    file contains random bytes to help test unforeseen corner cases.

     good-1-lzma2-1.xz has two LZMA2 chunks, of which the second sets
     new properties.
