bpf: Update selftests to reflect new error states
commit d7a5091351756d0ae8e63134313c455624e36a13 upstream.
Update various selftest error messages:
* The 'Rx tried to sub from different maps, paths, or prohibited types'
is reworked into more specific/differentiated error messages for better
guidance.
* The change into 'value -4294967168 makes map_value pointer be out of
bounds' is due to moving the mixed bounds check into the speculation
handling and thus occuring slightly later than above mentioned sanity
check.
* The change into 'math between map_value pointer and register with
unbounded min value' is similarly due to register sanity check coming
before the mixed bounds check.
* The case of 'map access: known scalar += value_ptr from different maps'
now loads fine given masks are the same from the different paths (despite
max map value size being different).
