taint/module: remove unnecessary taint_flag.module field

The TAINT_RANDSTRUCT and TAINT_FWCTL flags are mistakenly set in the
taint_flags table as per-module flags.  While this can be trivially
corrected, the issue can be avoided altogether by removing the
taint_flag.module field.

This is possible because, since commit 7fd8329ba502 ("taint/module: Clean
up global and module taint flags handling") in 2016, the handling of
module taint flags has been fully generic.  Specifically,
module_flags_taint() can print all flags, and the required output buffer
size is properly defined in terms of TAINT_FLAGS_COUNT.  The actual
per-module flags are always those added to module.taints by calls to
add_taint_module().
