Subject: [PATCH] fix build on gcc-10 (-fno-common)

gcc-10 changed the default from -fcommon to fno-common:
  https://gcc.gnu.org/PR85678

As a result build fails as:

    ld: i3lock-unlock_indicator.o:(.bss+0xc): multiple definition of
      `input_position'; i3lock-i3lock.o:(.bss+0x3c): first defined here

The change turned one of definitions into declaration.
