Fix qi packages detection.

This PR fix qi packages detection, /var/qi/installed_packages.list is no more needed and we read /usr/pkg directory directly.

Hello. pkgsrc ( a package manager used by NetBSD, but also support Linux ) also use /usr/pkg. In addition, /usr/pkg is commonly used by BSD systems.

Line 581 in 7566f10

if (!(options->disabled & FF_PACKAGES_FLAG_PKGSRC_BIT)) packageCounts->pkgsrc += getNumElements(baseDir, "/usr/pkg/pkgdb", DT_DIR);

In this case, I'm afraid that I can't support qi any more.

we read /usr/pkg directory directly

Are you one of the maintainers of qi?

Qi seems to be little different. Qi install packages by extracting packages into /usr/pkg/name_of_package.

No, I'm not, the dragora folks (people who use qi) seems not care. If the qi package detection support will be dropped, I'll maintain the patch for my self.

I was the one who previously suggest to use /var/qi/installed_packages.list months ago. Officially, /var/qi/installed_packages.list doesn't exist. I just hack the qi package manager to make that file so I can read what packages are installed.

/usr/pkg is a very common path name, and has been used by other package managers.

I dont think counting elements in /usr/pkg is a good idea. If existing method doesnt work any more, I will delete it.

Thanks for reporting!
