selftests/bpf: Add ASSERT_TEXT_EQ()

Text comparisons in test_progs repeat the same two statements:
compare_text_to_expected() to print the diff, then an assert to record
the failure. ASSERT_OK() on the raw return also appends a stale errno
to the failure output.

Add ASSERT_TEXT_EQ() after ASSERT_HAS_SUBSTR(). The assert cannot move
into compare_text_to_expected() itself: the helper is linked into
standalone binaries without test__fail(), and the framework unit test
checks the raw mismatch return. Convert the 3 test_progs call sites
plus test_ctx__dump_and_compare(), so multi-line dumps fail with a
diff; prog_tests_framework.c keeps calling the helper directly.
