cos-gpu-installer: reference locked file in the main function

Sending https requests might trigger Go garbage collection and
close unrefernced locked file so that the lock is released.
This results in allowing two installer instances running in one VM.

This CL makes the main function reference the locked file
and explicitly close it so that the lock won't be accidentally
released.

BUG=b/237702412
TEST=Repeatedly trying to start a second installer during
the driver installation process.
