selftests/bpf: Separate var preset parsing in veristat

Browse source

Refactor var preset parsing in veristat to simplify implementation.
Prepare parsed variable beforehand so that parsing logic is separated
from functionality of calculating offsets and searching fields.
Introduce rvalue struct, storing either int or enum (string value),
will be reused in the next patch, extract parsing rvalue into a
separate function.
