Y4M loader: add support for images with no framerate info
I got one from gpac:
```
$ gpac -i lena.490x490.unc uncvdec -o /tmp/output.y4m
$ xxd /tmp/output.y4m
00000000: 5955 5634 4d50 4547 3220 5734 3930 2048 YUV4MPEG2 W490 H
00000010: 3439 3020 4131 3a31 2049 7020 4334 3230 490 A1:1 Ip C420
00000020: 6d70 6567 320a 4652 414d 450a 7272 7170 mpeg2.FRAME.rrqp
...
```
Tested:
Before:
```
$ IMLIB2_DEBUG=31:0 IMLIB2_LOADER_PATH=./src/modules/loaders/.libs/ LD_LIBRARY_PATH=./src/lib/.libs:${LD_LIBRARY_PATH} ./src/bin/imlib2_view /tmp/output.y4m
No loadable image
```
After:
```
$ IMLIB2_DEBUG=31:0 IMLIB2_LOADER_PATH=./src/modules/loaders/.libs/ LD_LIBRARY_PATH=./src/lib/.libs:${LD_LIBRARY_PATH} ./src/bin/imlib2_view /tmp/output.y4m
```
