libbacktrace patch committed: Set table field for RLE sequence

[Ian Lance Taylor]

In libbacktrace, the RLE sequence code in the zstd decompressor failed
to initialize the table field. This patch from Ivan Molodetskikh fixes
the problem. Ran libbacktrace tests on x86_64-pc-linux-gnu. Committed
to mainline.

Ian

* elf.c (elf_zstd_unpack_seq_decode): Set table field for RLE
sequence.
* zstdtest.c (tests): Add rle-sequence-tables test.
