Bug Description

Like bug 2023680, which is for ARM64 instances

This test_verifier test in ubuntu_bpf is also failing sub-test 192 and 467, but with AMD64 (passed with AWS / Azure AMD64 instances) on L-gcp.

 #192/p bpf_get_task_stack return R0 range is refined FAIL
 Failed to load prog 'Permission denied'!
 func 'bpf_iter_task' arg0 has btf_id 141654 type STRUCT 'bpf_iter_meta'
 cannot access ptr member buf with moff 0 in struct seq_file with off 0 size 1
 R1 is of type seq_file but seq_file is expected
 verification time 903 usec
 stack depth 8
 processed 27 insns (limit 1000000) max_states_per_insn 0 total_states 2 peak_states 2 mark_read 2

 #467/p d_path accept FAIL
 Failed to load prog 'Permission denied'!
 func 'dentry_open' arg0 has btf_id 154800 type STRUCT 'path'
 cannot access ptr member mnt with moff 0 in struct path with off 0 size 1
