libsemanage: fix linker script symbol versions

Browse Source 
In previous work to cleanup the exports and linker scripts, I introduced
a regression causing symbols to be named in both the 1.0 and 1.1
sections. This went un-noticed and was reported by
nicolas.iooss@m4x.org.

Previous patches checked for correctness by:
This was checked by generating an old export map (from master):
nm --defined-only -g ./src/libsemanage.so | cut -d' ' -f 3-3 | grep -v '^_' > old.map

Then creating a new one for this library after this patch is applied:
nm --defined-only -g ./src/libsemanage.so | cut -d' ' -f 3-3 | grep -v '^_' > new.map

And diffing them:
diff old.map new.map

However, this discards the version information. Nicolas points out a
better way, by using objdump so we can see the version information. A
better sequence of commands for checking is as follows:

git checkout 1967477913
objdump -T ./src/libsemanage.so | grep LIBSEMANAGE | cut -d' ' -f 8- | sed 's/^ //' > map.old

git checkout origin/master
objdump -T ./src/libsemanage.so | grep LIBSEMANAGE | cut -d' ' -f 8- | sed 's/^ //' > map.new

diff map.old map.new
