kconfig: include <strings.h> to fix bcmp build error on Clang

[Z-Script Zs]

Hi,

This patch fixes a build error caused by missing <strings.h> when compiling 

with Clang in strict ISO C environments such as Termux or Android.

The function 'bcmp' is used in scripts/kconfig/confdata.c, but without

including <strings.h>, the build fails under strict C99 rules due to an

implicit declaration.

I'm 12 years old and just starting to learn Linux kernel development.  

This is my first patch submission. I'd be very grateful for any feedback or corrections.

Thank you for your time and for maintaining this incredible project.

Best regards,  

Abhigyan Ghosh
