Replace LP_DISABLED_VCS_PATH with array variable

Having a config var that stores paths as one string separated by a
specific char is a error waiting to happen. It's much safer (and easier
to read) to use a true array. This would be a breaking change, so
deprecate LP_DISABLED_VCS_PATH, and add LP_DISABLED_VCS_PATHS array. Add
a conversion function in the config file loading section.

An example config change would be:
    LP_DISABLED_VCS_PATH="/my/one/path:/my/other/path"
to
    LP_DISABLED_VCS_PATHS=("/my/one/path" "/my/other/path")
