travis: update asan build to Fedora 32

With the updated gcc to version 10 the AddressSanitizer plugin seems to
have switched the OneDefionitionRule to 2, which includes reports for
definitions with the same size.

In our case that breaks heavily due to our usage in eina_module:

==147526==ERROR: AddressSanitizer: odr-violation (0x7fca71b29300):
  [1] size=8 '__eina_module_shutdown' ../src/modules/ecore_imf/xim/ecore_imf_xim.c:821:1
  [2] size=8 '__eina_module_shutdown' ../src/modules/evas/engines/buffer/evas_engine.c:185:1

Disabeling it for our runs.
