[PATCH 4/4] fedora: Update buildsrpm.sh for dynamic versioning

[Prarit Bhargava]

fwts.spec requires a manual update for the major, minor and subminor
versions every release.  This can be avoided by dynamically updating the
spec file every build.

I have modified buildsrpm.sh to determine the current version of fwts from the
value of FWTS_VERSION in src/lib/include/fwts_version.h.  This value is used to
substitute values for major, minor, and subminor values in fwts.spec.in.
The buildsrpm.sh script creates fwts.spec which is then used to build rpms.

Also update the global .gitignore file to ignore the dynamically created
fwts.spec file.
