[PATCH] Add necessary headers for major()/minor() on Solaris to xf86Xinput.c

[Alan Coopersmith]

Without these, after commit fdb4ec86c29d85c, it fails to build on Solaris,
with errors of:
xf86Xinput.c: In function 'xf86stat':
xf86Xinput.c:816:5: error: implicit declaration of function 'major' [-Werror=implicit-function-declaration]
xf86Xinput.c:817:5: error: implicit declaration of function 'minor' [-Werror=implicit-function-declaration]
