executor: fix TestGenerate errors

These pseudo syscalls implementation was not previously tested in
pkg/csource, so let's first fix the bugs before enabling tests
for them.

Log Message:
-----------
prog: generate no_generate syscalls for tests

Only consider disable and no_generate attributes during fuzzing, but
permit the generation of such syscalls for tests (specifically, this
is needed for compilation tests in pkg/csource).

prog: change kfuzztest syscall ID caching for prog.Target

Caching the value only once is problematic when we deal with several
targets at the same time (e.g. in tests).

As the ID anyway refers to a syscall that is not dynamically added,
but rather already exists in sys/linux, let's drop caching completely
and query the ID in lazyInit().
