Subject: pactest : Use tarfile module.

Previously, tar was called manually with os.system. This caused one fork per
package/db creation, which is costly, especially on cygwin. Besides, it also
caused some problems with directory with whitespaces (that could also be
fixed with quotes, but well..)
Using tarfile module is cleaner and more efficient, and still easy enough.

Benchmark (time make check) :
- windows / cygwin
