* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
This gives speed improvement and fixes potential bugs.
For example: https://bugs.openmw.org/issues/3351
Updating our openscenegraph package would fix this too, but
it breaks some packages (i.e. simgear, bumping the version does
not help). Besides, fork has patches for better performance.
