booster: Remove fcntl.h from include path

We define the O_CREAT, etc. flags so that we can remove fcntl.h from the
include path. fcntl.h has certain defines and other lines of
code that redirect application's open and open64 calls to the
syscalls defined by libc.

For us, thats not a Good Thing (TM).
