perf test: Fix sys_enter_openat event test for musl
The "syscalls:sys_enter_openat event fields" test calls
openat(AT_FDCWD, "/etc/passwd", O_RDONLY | O_DIRECTORY)
and verifies that the flags of the captured event are matching.
This fails for musl, where the openat syscall wrapper always adds
O_LARGEFILE.
Update the check to allow for additional flags, the access mode flags
must be unchanged.
