[PULL 15/16] .travis.yml: single thread build-tcg

[Alex Bennée]

I've theorised that a parallel build-tcg is somehow getting confused
when two fedora-30 based cross compilers attempt to build at the same
time. From one data-point so far this may fix the problem although the
plugins job runs quite close to timeout.
