Add libtool to eext base-image

[dzmaroz]

Libtool is needed to build curl in eext.

Is the curl spec file using libtool in %prep itself ? Only %prep is run in the base image, all other deps are satisifed by mock itself.

The prep in base-image is just a nice-to-have thing to see if patches apply cleanly in create-srpm itself, otherwise we'll defer prep to actual run of mock and fail a little late.
An alternative is to use --skip-build-prep option to eext.

Yes, in %prep itself.
Thanks for clarification. Then I'll just drop this PR and use --skip-build-prep instead. A little delay in %prep doesn't seem to be critical.
