[COMMITTED] poked: change the default socket path

[Mohammad-Reza Nabipoor]

This commit changes the default socket path from `/tmp/poked.ipc'
to `/tmp/poked-$UID.ipc'.

2023-02-01  Mohammad-Reza Nabipoor  <mnabipoor@gnu.org>

        * poked/poked.c: Include `<unistd.h>' for `getuid'.
        (poked_options): Remove const-qualifier from `socket_path'.
        (poked_options_init): Change the default socket path to have
        UID in the path.
