libc: match ioctl request type to contrib type

Browse Source 
There is a type mismatch as in the FreeBSD contrib code the type of the
request is 'unsigned long'. So far, only I/O controls where the request
falls into the signed range where used and this was not a problem.

Some of the SNDCTL requests, however, have the bit set.

Fixes #3887.
