SuiteSparse: update to 6.0.1.

[tornaria]

Testing the changes

• I tested the changes in this PR: briefly

SuiteSparse is used in sagemath through python3-cvxopt -- I ran the sagemath testsuite with this update.

What shall we do about this:

SuiteSparse-devel and mongoose-devel conflict for
  /usr/lib/libmongoose.a
  /usr/lib/libmongoose.so
Error: Process completed with exit code 1.

[tornaria]

The CI failures look harmless:

• A file conflict that we already have; I don't know how this can be resolved.

SuiteSparse-devel and mongoose-devel conflict for
  /usr/lib/libmongoose.a
  /usr/lib/libmongoose.so

• Package igraph used to depend on a shlib that bumped soname so it would merit a revbump. However, there is igraph: update to 0.10.2. #40224 to update igraph, the new version does not depend on SuiteSparse at all.

Trying to install dependants of SuiteSparse-devel:
igraph-0.9.8_1: broken, unresolvable shlib `libcxsparse.so.3'
Transaction aborted due to unresolved shlibs.

[tornaria]

Apologies for the multiple force-push. Just two changes:

• added more shlibs to common/shlibs, they will be used by octave in octave: update to 7.3.0. #40720
• annotate the conflict between SuiteSparse-devel and mongoose-devel

Hopefully with these two changes CI will pass.

Now the three CI failures are just the expected igraph-0.9.8_1: broken, unresolvable shlib libcxsparse.so.3'` because of the soname change. This will resolve once #40224 is merged, since igraph-0.10.2 does not link to SuiteSparse at all, it seems a waste to revbump igraph here.

[Piraty]

of course igraph requires a revbump, in igraph-0.9.8_1, libigraph.so.0.0.0 links libcxsparse.so.3
EDIT: ah i see, igraph vendors CSparse. no revbump needed now that igraph update is merged

[Piraty]

can you please rebase, so CI runs again

Done, everything passed.

Thanks!
