tools: termios_linux.h: Fix compilation on non-glibc systems
TCGETS2 is defined in header file asm/ioctls.h provided by linux kernel.
On glib systems it is automatically included by some other glibc include
header file and therefore TCGETS2 is present in termios_linux.h when
linux kernel provides it.
On non-glibc systems (e.g. musl) asm/ioctls.h is not automatically included
which results in the strange error that BOTHER is supported, TCGETS2 not
defined and struct termios does not provide c_ispeed member.
tools/kwboot.c: In function 'kwboot_tty_change_baudrate':
tools/kwboot.c:662:6: error: 'struct termios' has no member named 'c_ospeed'
662 | tio.c_ospeed = tio.c_ispeed = baudrate;
| ^
Fix this issue by explicitly including asm/ioctls.h file which provides
TCGETS2 macro (if supported on selected architecture) to not depending on
glibc auto-include behavior and because termios_linux.h requires it.
With this change it is possible compile kwboot with musl libc.
