[1/1] package/libgphoto2: fix build with gcc >= 14

The commit adds an upstream patch to fix the following build failure:

jl2005c/jl2005bcd_decompress.c: In function 'jl2005bcd_decompress':
jl2005c/jl2005bcd_decompress.c:161:46: error: passing argument 3 of 'jpeg_mem_dest' from incompatible pointer type [-Wincompatible-pointer-types]
  161 |         jpeg_mem_dest (&cinfo, &jpeg_header, &jpeg_header_size);
      |                                              ^~~~~~~~~~~~~~~~~
      |                                              |
      |                                              long unsigned int *

Tested-by: Edgar Bonet <bonet@grenoble.cnrs.fr>

I did a build-test as follows:

    cat >gphoto2_defconfig <<EOF
    BR2_mips64el=y
    BR2_TOOLCHAIN_BUILDROOT_UCLIBC=y
    BR2_PACKAGE_JPEG=y
    BR2_PACKAGE_LIBGPHOTO2=y
    EOF
    make defconfig BR2_DEFCONFIG=gphoto2_defconfig
    make libgphoto2

On commit adf99a634b357 (master at the time of the test), this test
reproduces the build failure seen on the autobuilder.[1] Applying this
patch, the build succeeds.

Regards,

Edgar Bonet.

Thanks Edgar for the test!

We still had this build issue in our autobuilder today.

https://autobuild.buildroot.org/results/7be/7be5175afa4802389caefb5c0b310f4605d8c5e4/build-end.log

Applied to master. Thanks.

Best regards,
Romain
