[LTP] [PATCH v4] Add PATH to tst_rhost_run.sh

[WEI GAO]

From: coolgw <wegao@suse.com>

When run single test case use command such as:
LTP_SHELL_API_TESTS=shell/net/tst_rhost_run.sh make test-shell
Error msg such as "ns_create: command not found" will popup, so
need update PATH before call ns_create etc..

More important:
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.
