Build: fix distribution of asn1/asn1c files

All the headers are now listed in _SOURCES variable.
It seems weird but this is what GNU Automake manual suggests in section
9.2 Header files:
  Headers used by programs or convenience libraries are not installed.
  The noinst_HEADERS variable can be used for such headers.
  However when the header actually belongs to a single convenience library
  or program, we recommend listing it in the program’s or library’s
  _SOURCES variable (see Program Sources) instead of in noinst_HEADERS.
  This is clearer for the Makefile.am reader.
  noinst_HEADERS would be the right variable to use in a directory containing
  only headers and no associated library or program.
