[PATCH v3 01/10] travis: Run bootstrap instead of autogen.sh

[Alexander Graf]

Commit 35b909062e7b3 ("gnulib: Upgrade Gnulib and switch to bootstrap tool")
changed the build flow from running ./autogen.sh to running ./bootstrap
but missed to update .travis.yml. Adapt it accordingly.

Fixes: 35b909062e7b3 ("gnulib: Upgrade Gnulib and switch to bootstrap tool")

v1 -> v2:

  - use local gnulib copy (saves ~3m git checkout time)

v2 -> v3:

  - add comments to why we still use the system gnulib
