modif: keep /sys/module/nvidia* if prop driver and no no3d (#6387)HEADmaster

It has been reported in #6372 that after upgrading the nvidia
proprietary driver from version 550.78 to 550.90.07, programs using
hardware acceleration fail unless paths in `/sys/module/nvidia*` are
accessible.  Example:

    $ firejail --noprofile prime-run /bin/glxdemo
    [...]
    X Error of failed request:  BadValue (integer parameter out of range for operation)
      Major opcode of failed request:  150 (GLX)
      Minor opcode of failed request:  3 (X_GLXCreateContext)
      Value in failed request:  0x0
      Serial number of failed request:  22
      Current serial number in output stream:  23
    [...]

Meanwhile, the AMD proprietary driver (AMDGPU Pro) seems to depend on
`/sys/module/amdgpu` for OpenCL (though it is unclear how to detect that
driver).  See commit 95c8e284d ("Allow accessing /sys/module directory",
2018-05-08) and commit 9dd581d25 ("Allow AMD GPU usage by Blender",
2018-05-08) from PR #1932.

So whitelist `/sys/module/nvidia*` by default if the nvidia proprietary
driver is detected and `no3d` is not used.

Note: The driver check is copied from src/firejail/util.c (see #841).

To keep the current behavior (that is, block all modules), add
`blacklist /sys/module` to globals.local.

Fixes #6372.
