btattach: Update for glibc 2.42 compatibility
btattach is not setting the baud rate correctly on systems with newer
glibc such as Ubuntu 26.04. In glibc 2.42 the baud rate termios.h
constants changed value, B115200 was 0x1002 which was the struct
termios c_cflag enum bits, but in 2.42 they changed cfsetspeed() to
accept arbitrary rates and not just the baud enum values, and B115200
was changed to the value 115200. This means you can no longer set the
speed with c_cflag |= B115200 and should use cfsetspeed() to be
compatible with both versions.
