Include LOCPATH in default test environment.

Tests run using the default $(make-test-out) automatically get
GCONV_PATH and LC_ALL set, whether or not those environment variables
are actually needed for the individual test.  However, they do not get
LOCPATH set, meaning that a large number of tests have -ENV settings
just to set LOCPATH.

This patch moves LOCPATH into the default environment used for all
tests, on the principle that like GCONV_PATH any settings needed to
use files associated with the newly built library, rather than any old
installed files, are appropriate to use by default.

A further motivation is that various tests using .sh files also set
some combination of LC_ALL, GCONV_PATH and LOCPATH.  Preferably .sh
files should also use the default environment with any additions
required for the individual test.  Now, it was suggested in
<https://sourceware.org/ml/libc-alpha/2014-05/msg00715.html> that
various Makefile variables used in testing should be derived by
composing the -before-env and -after-env variables used when explicit
environment settings are required.  With such a change, it's also
natural for those variables to include the default settings (via some
intermediate makefile variable also used in make-test-out).

Because some .sh files only set variables that correspond to the
default settings, or a subset thereof, and this applies to more of the
.sh files once LOCPATH is in the default settings, doing so reduces
the size of a revised version of
<https://sourceware.org/ml/libc-alpha/2014-05/msg00596.html>: scripts
only needing the (expanded) default settings will not need to receive
the separate -before-env and -after-env variables, only the single
variable they do at present.  So moving LOCPATH into the default
settings can reduce churn caused by subsequent patches.

Tested x86_64 and x86.
