uclibc: add kernel module syscall wrappers

Revert the decision to remove the wrappers, but remove the extra Config symbol and add it by default. Required for kmod package.

--- Comment #5 from Thomas Petazzoni <[email protected]> --- This issue has been fixed by the uClibc-ng change. The original reporter did not provide additional details as to how to reproduce the problem with the fixed uClibc-ng. Therefore, I'm closing this bug.
