Create stubs for signal.h

Add a crate with stubbed functions for the float.h header.

Add implementations of sprintf and snprintf so that we can get a bit
closer to compiling libc-test.

The current implementation of open requires the user to pass all three
args to the function. It should use a va_list and allow a user to
provide only the filename and flags.
