Item14530: Fix Query.pm to show correct "File System Paths"

[bixycler]

• Fix bootstrapping values of $Foswiki::cfg{$bsdir} in function getspec()

@gac410, would you please review this small patch to fix the "known issue" in Item14530.

Before merging the request may I suggest changing bsdir/BSDIRS to a more descriptive name? What does 'BS' stands for? I would suspect it is a shorthand for 'base' but could also be 'basic', 'big storage', etc...

bixycler, here is a status update on merge plans for 2.2. I did a trial merge and some testing. I ran into a couple of issues.

1. On a site that is migrating from a 2.1/2.0 configuration, the RootDir remains unset. It doesn't cause any problems initially, but the default value remains /home/httpd/foswiki, which might cause issues when saved. I added some code to initialize the setting during config load, and hit a 2nd issue.
2. pseudo-install.pl does a "require" to check for dependencies, and this causes Foswiki modules to initialize before LocalSite.cfg is created. My fix for point 1 went into a hard loop.

Anyway, I do plan to get this into 2.2, but it needs a bit more work, and we should probably clean up pseudo-install.pl to use Foswiki::Configure::FileUtil::findFileOnPath() to resolve dependencies rather than "require", which triggers all sorts of initialization code prematurely.
