enlarge gsm0808 msgb headroom
It should be large enough to prepend a struct osmo_scu_prim to pass down an
SCCP stack (see libosmo-sccp). 264 should suffice, but pick the next larger
power-of-two instead.
In osmo-msc, I would like to prepend an osmo_prim to the msgb created by
gsm0808 API, but turns out the headroom is too small:
msgb(0x61700001b660): Not enough headroom msgb_push (126 < 264)
Instead of always copying a msgb that has just that instant been created, it
makes more sense to allocate sufficient headroom in the first place.
