TEST_TOOLS_COLONDB: Add tests for sss_colondb_*

There are three functions at API of colondb wrapper:
 * sss_colondb_open()
 * sss_colondb_readline()
 * sss_colondb_writeline()

This patch adds tests for all of them.

We test those cases:
 * open nonexisting file for read
 * open nonexisting file for write
 * open existing empty file for read
 * open existing file with records for read
 * open existing empty file for write
 * open existing file with records for write
 * write to empty file
 * write to file with existing records
 * sss_colondb_open()
 * sss_colondb_readline()
 * sss_colondb_write_line()
 * write to empty file and read it
