um: drivers: call kernel_strrchr() explicitly in cow_user.c
Building ARCH=um on glibc >= 2.43 fails:
arch/um/drivers/cow_user.c: error: implicit declaration of
function 'strrchr' [-Wimplicit-function-declaration]
glibc 2.43's C23 const-preserving strrchr() macro does not survive
UML's global -Dstrrchr=kernel_strrchr remap from arch/um/Makefile.
Call kernel_strrchr() directly in cow_user.c so the source no longer
depends on the -D rewrite.
Fixes: 2c51a4bc0233 ("um: fix strrchr() problems")
