Build: Make version.h a configuration header

Use the proper tool for the job and make libsigrok/version.h
a secondary configuration header, so that autoconf's AC_DEFINE
machinery can be used to generate it.  Note that the header
template is still hand-written, enabling fine control of the
content.
