ci: Combine 32 bit build with centos build #17757

   There are a lot of ci builds run on travis for a single commit and some seem overlapping. I think we can turn the centos build into a 32-bit linux build and remove the 32-bit build to avoid travis bottlenecks.

   Useful skills:

   CentOS package manager, gcc cross-compilation

   Concept ACK.

   The ARM build is also 32 bit isn’t it?

   Jup, but I think as long as we ship the i686 gitian package, it wouldn’t hurt to also have one i686 cross compile

   Should this be a depends or no-depends build? As discussed in #17900, neither/nor seems to be optimal: a depends build is against one of the major initial goals of the CentOS build (https://github.com/bitcoin/bitcoin/pull/17900#issuecomment-572666614, #17628 (comment)), whereas a no-depends build is hardly possible considering that we would need all libraries already available in the desired target architecture, namely i686 (https://github.com/bitcoin/bitcoin/pull/17900#issuecomment-572697411).
