tt: Fixup tt build for new includes locations

Some files were trying to access the global includes directy in the
build area with things like #include <api/c/tt_c.h>, which is now
wrong.  Se we fix all of those up.  tt_c.h and tttk.h are now global,
so we no longer need to root around various build dirs to find them.

TT builds again.
