  Log Message:
  -----------
  [libc] Enable spawn lib in riscv

In this patch we add support for the spawn lib in riscv.

Only small changes were required, the biggest one was to use of dup3
instead of dup2, if the latter is not available. This follows our
implementation of dup2.

  Changed paths:
    M libc/config/linux/riscv64/entrypoints.txt
    M libc/src/unistd/linux/fork.cpp
    M libc/test/src/unistd/syscall_test.cpp

  Log Message:
  -----------
  [libc] Enable __llvm_libc_syscall and fork

This patch enables the remaining calls from unistd.

The test cases had to be updated to:
1. Use SYS_symlinkat if SYS_symlink is not available
2. Use SYS_readlinkat if SYS_readlink is not available
3. Use SYS_unlinkat if SYS_unlink is not available
4. Use SYS_openat if SYS_open is not available

We also abort compilation if neither of the syscalls mentioned above are
available.
