[gtk-doc/scangobj-quotes-fix: 2/2] gtkdoc-scangobj: allow to pass --{c, ld}flags multiple times

[Marco Trevisan <marcotrevi src gnome org>]

commit 0ffa6eb14cb8234e8bb7767ec683996e9830c725
Author: Marco Trevisan (Treviño) <mail 3v1n0 net>

    gtkdoc-scangobj: allow to pass --{c,ld}flags multiple times
    
    Instead of supporting the cflags argument just once, allow to pass it multiple
    times. This allows build systems like meson to append cflags using
    `scanobjs_args` the parameter.
    
    Updated tests accordingly to check this.
