[Buildroot] [PATCH 1/4] support/testing: add builtin armv5 kernel 4.19 with entropy

More and more packages being tested by the test infra, e.g. syslog-ng,
need entropy at startup, usually reading from /dev/random.

Some test cases can also depend on a kernel version newer than the
builtin ones already provided by the test infra:
 - 3.11.0 for armv5;
 - 4.0.0 for armv7.

Add a new builtin kernel to be used by such test cases.
Add it for armv5 so most test cases that switch to use this kernel can
keep using BASIC_TOOLCHAIN_CONFIG.
Use the same kernel version and kernel config as qemu_arm_versatile plus
HW_RANDOM_VIRTIO for VirtIORNG to be usable.
Copy the actual binary file from the syslog-ng runtime test at current
master @ 29e1cb8884.
Since there is already a 'kernel-versatile' file and we must keep it
with this name for reproducibility purposes, create a simple naming
convention for newer builtin kernel images and dtb files:
kernel-<defconfig>-<kernel_series_version>
<dtb_name>-<kernel_series_version>.dtb
Pass '-device virtio-rng-pci' to qemu when this kernel is used.
