Adding override for lintian false positive on libvec.so

[ldematte]

Executing lintian on our deb distribution after #108088 was merged raises the following warning (treated as error): shared-lib-without-dependency-information

From the lintian docs:

The listed shared library doesn't include information about the
other libraries against which it was linked.
More specifically, "ldd foo.so" should report such other
libraries. In your case, it reports "statically linked".
The fix is to specify the libraries. One way to do so is to add
something like "-lc" to the command-line options for "ld".

It's true that ldd libvec.so does report "statically linked", but that's correct in our case: we do not reference any external symbol, not event from the standard C library. Googling around, this is commonly treated as a false positive in similar cases, so I'm adding an override for this rule for the libvec.so

Closes #108514
