[PATCH weston v2] build: honour libinput header location

[Emil Velikov]

From: Jan Engelhardt <jengelh at inai.de>

Add the respective CFLAGS to the build, otherwise it will error out as
seen below.

src/libinput-seat.c:30:22: fatal error: libinput.h: No such file or directory

v2: add the CFLAGS only as needed, suggested by Pekka
