igt/vgem_basic: Load and unload the module first

To ensure the module exists, first load it. Then when we try to unload
the module (to check that our modprobe interface works), we will not get
spurious failures due to -ENOENT (in this case meaning the module did
not exist):

(vgem_basic:18361) igt-core-DEBUG: Starting subtest: unload
(vgem_basic:18361) igt-kmod-DEBUG: Could not remove module vgem (No such file or directory)
Test requirement not met in function test_unload, file vgem_basic.c:331:
Test requirement: module_unload() == 0
Last errno: 2, No such file or directory
