Revert "gsm48: move to hex TMSI representation"

This is a "flag" day change. Old OpenBSC break with new libosmocore because suddenly there is the 0x in front. I am afraid we need to find a better solution here.
I think we will need to create a gsm48_mi_to_string variant that takes a mode parameter to enable the TMSI mode and deprecate the old method.

Right now we should not break old versions of OpenBSC.

This reverts commit 78ad042f94afd5bf7de477ae634e9d2fdd9c9dc4.
