[LTP] [PATCH v3] Add containers/share to PATH when call init_ltp_netspace

[Petr Vorel]

Hi Wei,

There are 2 unrelated changes, they should be separated (in 2 commits).
We are sometimes benevolent on this, if the other change is tiny,
but these are 2 functional changes, they should really be separated.

Also, the subject (first line of the patch) is too long and describe only one
change.

> When run single test case use command such as:
> LTP_SHELL_API_TESTS=shell/net/tst_rhost_run.sh make test-shell
Instead of the description how to run tst_rhost_run.sh
(which now with the PATH can be run simply as
./lib/newlib_tests/shell/net/tst_rhost_run.sh)
more important is to say:
1) LTP shell API tests depend on properly compiled LTP.
Therefore this is just a workaround to make visible that some tool is missing.

2) I wonder if there is way to properly fix this dependency in make.
I guess test-shell target should depend on (at least): ns_create ns_exec
ns_ifmove.

PATH line will get quite long, I'd use variable for path to root.
It will be also more readable (similar to Makefiles, which have top_srcdir
variable).

root="$(dirname $0)/../../../../"
PATH="$root/testcases/lib/:$root/testcases/kernel/containers/share/:$PATH"
