	Some kernels builds might inline vfs_getattr call within fstat syscall code path, so fentry/vfs_getattr trampoline is not called. Add security_inode_getattr to allowlist and switch the d_path test stat trampoline to security_inode_getattr. Keeping dentry_open and filp_close, because they are in their own files, so unlikely to be inlined, but in case they are, adding security_file_open. Adding flags that indicate trampolines were called and failing the test if any of them got missed, so it's easier to identify the issue next time.

2020-08-25	selftests/bpf: Add test for d_path helper	Jiri Olsa
	Adding test for d_path helper which is pretty much copied from Wenbo Zhang's test for bpf_get_fd_path, which never made it in. The test is doing fstat/close on several fd types, and verifies we got the d_path helper working on kernel probes for vfs_getattr/filp_close functions.
