[LTP] [PATCH] network/gre01: fix device type setting

[Alexey Kodanev]

Since the include of tst_net.sh moved to virt_lib.sh, setting
correct GRE device type should be moved there too, i.e. after
sourcing tst_net.sh and before virt_lib.sh. Otherwise IPv6
test-case won't work.

Fixes: ce920a5a430c ("network/virt_lib.sh: Process getopts parameters with TST_OPTS and TST_PARSE_ARGS")
