Tim Armstrong c43c03c5ee IMPALA-3926: part 2: avoid setting LD_LIBRARY_PATH
This removes LD_LIBRARY_PATH and LD_PRELOAD from the
developer's shell and cleans it up. With the preceding
change, toolchain utilities like clang can be run without
a special LD_LIBRARY_PATH.

This fixes a bug where libjvm.so was registered as a
static instead of a shared library, which adds it to the
RUNPATH variable in the binary, which provides a default
search location that can be overriden by LD_LIBRARY_PATH.

Impala binaries don't have the rpath baked in for some
libraries, including Impala-lzo, libgcc and libstdc++.
, so we still need to set LD_LIBRARY_PATH when running
those. That is solved with wrapper scripts that sets
the environment variables only when invoking those
binaries, e.g. starting a daemon or running a backend
test. I added three scripts because there were 3 sets
of environment variables. The scripts are:
* run-binary.sh: just sets LD_LIBRARY_PATH
* run-jvm-binary.sh: sets LD_LIBRARY_PATH and CLASSPATH
* start-daemon.sh: sets LD_LIBRARY_PATH and CLASSPATH and
  kerberos-related environment variables.

The binaries, in almost all cases, work fine without
those tweaks, because libstdc++ and libgcc are picked
up along with libkuduclient.so from the toolchain (they
are in the same directory). I decided to leave good enough
alone here. run-binary.sh and friends can be used in
any remaining edge cases to run binaries.

An alternative to the 3 scripts would be to have an
uber-script that set all the variables, but I felt
that it was better to be specific about what
each binary needed. Cleaning the LD_LIBRARY_PATH
mess up has given me a distaste for scattershot
setting of environment variables. I am open to
revisiting this.

Testing:
* Ran tests on centos 7
* Manually tested that my dev env with
 LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu continued
 to work (for now). All ubuntu 16.04 and 18.04 dev
 envs that were set up with bootstrap_development.sh
 will be in this state.
