[arm64] Increase SD card image sizes for netboot, netboot-gtk

Alper Nebi Yasak requested to merge alpernebbi/debian-installer:arm64-netboot-image-size into master

The arm64 netboot build recently started failing when generating the SD card partition:

gen-hd-image -v -z -p 32768 -b partition -s "150000" -i "./tmp/netboot/netboot_images_concatenateable" -o "./dest/netboot//SD-card-images//partition.img"
gen-hd-image: Starting to generate image ./dest/netboot//SD-card-images//partition.img ...
gen-hd-image: Building filesystem ...
mkfs.fat 4.2 (2021-01-31)
/tmp/tmp.sbkFeJgWdQ has 16 heads and 32 sectors per track,
hidden sectors 0x0000;
logical sector size is 512,
using 0xf8 media descriptor, with 267232 sectors;
drive number 0x80;
filesystem has 2 32-bit FATs and 1 sector per cluster.
FAT size is 2056 sectors, and provides 263088 clusters.
There are 32 reserved sectors.
Volume ID is 680e35b9, no volume label.
Disk full
make[2]: *** [config/arm64//netboot.cfg:29: netboot_images_concatenateable] Error 1

Looking at previous builds shows the kernel, initrd and device-tree files used to barely fit into the partition when building for the previous kernel. So, this build error is most likely due to new module additions to the kernel udebs making the total size go over the capacity.

Increase the arm64 netboot and netboot-gtk image sizes to double their current size to let the boot files fit, with some space to spare.

Tested that make build_netboot and make build_netboot-gtk succeeds in an arm64 chroot, resulting netboot SD card images have about 50% free space.
