[PATCH 3/5] test: py: efiloader: prepare get_dmesg for more general usage

[Ahmad Fatoum <a.fatoum@barebox.org>]

Despite the generic sounding name, get_dmesg actually filter for the 'efit'
string, which is not always what's intended. Rename it to get_journalctl
to make the dependency clearer and make it more generic.
