pkg/host: Add stat to kallsyms rename map
pkg/host: Add stat to kallsyms rename map

On powerpc, the "stat" syscall is implemented by "sys_newstat" entry point.
This causes a test failure as we can't find "sys_stat" in kallsyms.

Add "stat" -> "newstat" to the kallsyms rename map to work around this.

Closes: #1083 ("pkg/host: TestSupportedSyscalls fails on ppc64le")
