Add option for setting zlib/zstd compression algorithms

[dveeden]

This allows one to select zlib or zstd.

[dveeden]

Example:

[dvaneeden@dve-carbon sysbench]$ ./src/sysbench --mysql-host=127.0.0.1 --mysql-user=root --mysql-password=root --mysql-compression --mysql-compression-algorithms=zstd --time=60 oltp_read_only run
sysbench 1.1.0-4228c85 (using bundled LuaJIT 2.1.0-beta3)

Running the test with following options:
Number of threads: 1
Initializing random number generator from current time


Initializing worker threads...
