build: fix ranap gen, use same for gen hnbap and rua gen

fix extraneous rebuild for each make invocation: touch the ranap.stamp file in
src/ as the make target suggests.

fix for 'make distcheck': ranap gen: move generated sources to builddir, not
srcdir. Thus we also -I the builddir include to pick up those headers.

hnbap and rua have the same situation as ranap (they generate numerous files
from a single make rule). Use the same makefile semantics for those two
(commit for ranap gen omitted the same changes for hnbap and rua).

The generated headers are thus moved to include/osmocom/*/, so adjust #include
statements accordingly (*_common.h, *_ies_defs.h).

Also move hnbap_common.h to include/osmocom/hnbap and rua_common.h to
include/osmocom/rua, since the *_ies_defs.h want to include them; and since
*_ies_defs.h are now in include/osmocom/*, we want a '<foo>' include now.

Also adjust gitignore.
