etnaviv: enable triangle strips only when the hardware supports it
Some hardware has a bug with triangle strips and it is signalled by the
flag BUG_FIXED8 whether this bug has been fixed. So only enable triangle
strips when this flag is set.
Thanks: Jonathan Marek and Christian Gmeiner for the pointers
v2: Add TODO to indicate that the handling should be refined
