glsl: rework parsing of blocks
Previously interface blocks were giving the global default flags of
uniform blocks. This meant we could not check for invalid qualifiers
on interface blocks because they always contained invalid flags.
This changes parsing so that interface blocks now get an empty
set of layouts.
