[LTP] [RFC PATCH v2 5/5] travis: Install all dependencies + add build with minimal dependencies

[Petr Vorel]

Currently travis has installed toolchain with libraries, glibc and
kernel headers so some of the packages listed are already installed.

Install all dependencies (headers and libraries).
The only exception is selinux support on 32bit build as as
libsepol1-dev:i386 conflict with libsepol1-dev for amd64, thus both
cannot be installed.

During reinstallation for build with minimal dependencies we need to
filter out some packages as toolchain package depends on it.

For minimal build chosen gcc 6 (relativelly recent gcc version, but not
too new).
