selftests/bpf: Limit URLS parsing logic to actual scope in vmtest

Browse Source 
The URLS array is only valid in the download_rootfs function and does
not need to be parsed globally in advance. At the same time, the logic
of loading rootfs is refactored to prepare vmtest for supporting local
rootfs.
