Jon Hunter a2b53ade55 virt: hvc_sysfs: Fix build for Linux v6.13 ...

In Linux v6.13, commit 94a20fb9af16 ("sysfs: treewide: constify
attribute callback of bin_attribute::mmap()") changed the type of the
'struct bin_attribute' argument of the bin_attribute:mmap function
pointer to const. Use conftest to detect if this argument is const or
not in the kernel the driver is being compiled against to fix the build.

Bug 4991705
