Stefan Eßer e11ad014d1 libc: return partial sysctl() result if buffer is too small 
Testing of a new feature revealed that calling sysctl() to retrieve
the value of the user.localbase variable passing too low a buffer size
could leave the result buffer unchanged.

The behavior in the normal case of a sufficiently large buffer was
correct.

All known callers pass a sufficiently large buffer and have thus not
been affected by this issue. If a non-default value had been assigned
to this variable, the result was as documented, too.

Fix the function to fill the buffer with a partial result, if the
passed in buffer size is too low to hold the full result.
