    build: Detect X11/XF86keysym.h to enable extra keys
    Support for special keyboard keys for actions such as Back,
    Forward, Refresh, Go Home, etc. depends on this header.
    
    We used to check for this header in configure.ac but
    this was lost when porting from autotools to meson
    (commit 857a90c2).
    
    Restore this support by checking for this header with meson.
    Also, indent fix style.
    
    Fixes #134
