epiphany: Do not bypass initialization of variable with __attribute__((cleanup))

This is reported with clang e.g.
../../../../../../../workspace/sources/epiphany/lib/ephy-web-app-utils.c:391:5: error: cannot jump from this goto statement to its label
    goto out;
    ^
../../../../../../../workspace/sources/epiphany/lib/ephy-web-app-utils.c:398:20: note: jump bypasses initialization of variable with __attribute__((cleanup))
  g_autofree char *app_file = g_build_filename (profile_dir, ".app", NULL);
                   ^
../../../../../../../workspace/sources/epiphany/lib/ephy-web-app-utils.c:385:5: error: cannot jump from this goto statement to its label
    goto out;
    ^
../../../../../../../workspace/sources/epiphany/lib/ephy-web-app-utils.c:398:20: note: jump bypasses initialization of variable with __attribute__((cleanup))                                                                                                                     g_autofree char *app_file = g_build_filename (profile_dir, ".app", NULL);
                   ^

Ensure that the initialization is deterministic for goto to work reliably
