Add support for zstd decompression
When compiled with HAVE_ZSTD=1, transparently decompress perf
records contained in PERF_RECORD_COMPRESSED and parse those then.
This way, we can finally open data files recorded with
`perf record -z`, which are often two orders of magnitude smaller
for the common `--call-graph dwarf` case.
