Update location for multicast tests.

While running networktest for multicast ;  "mc_member" test displays the
following error message multiple times
"cat: /opt/ltp/testcases/inetwork/multicast/mc_menmber/ManyGroups: No
such file or directory".
This is Because variable "TCsrc" is exported with incorrect path. Looks
like previously LTP test scripts installed and ran directly from source
directory . Now it installs mulicast test binary and script files to
"$LTPROOT/testcases/bin" directory. Hence the variable "TCsrc" needed to
be exported with above mentioned install path.
