change(newlib): support line endings modification only with VFS

Browse Source 
The configuration of newline endings for stdout and stdin is supported
only by the VFS drivers. The write and read syscalls in newlib
automatically convert LF to CRLF for stdout and CR to LF for stdin,
ignoring the configured newline settings. Therefore, make the options
for newline endings visible only when VFS is enabled.
