  Log Message:
  -----------
  [libc] Move fcntl implementation into the syscall_wrappers layer (#207878)

linux_syscalls::fcntl called SYS_fcntl unconditionally, breaking the
riscv32 full build where only SYS_fcntl64 exists. The syscall selection
and command translation already lived in internal::fcntl, so move that
implementation into syscall_wrappers/fcntl.h, delete the legacy
OSUtil/fcntl.h and OSUtil/linux/fcntl.cpp, and port the callers (fcntl
entrypoint, file.cpp, dup2.h) to linux_syscalls::fcntl.
