COMP: Simplify build-system removing TRAVIS_BUILD option

CFLAGS and CXXFLAGS env. variables are explicitly set in travis configuration

Explicit passing of "-Wno-deprecated" to ITK project is removed because
(1) it is done starting with ITK project 4.0 in
InsightSoftwareConsortium/ITK@8a135bcb1 (ENH: Detect/use recommended
compiler flags) from 2011-08-20
and (2) Seg3D is build against ITK 5.x. See 3b6512c (Update ITK version to 5.1.0)
