[File] Patch: whitelist madvise() system call in seccomp filter

[Leandro Pereira]

Hi.

Some malloc implementations will call madvise() to enable the use of
huge pages, and if a memory allocation in file triggers the threshold
in the allocator, file(1) receives an untrappable SIGSYS.

The attached patch whitelists the madvise() syscall so that file(1) can
be executed on those systems with the seccomp filter enabled.

Cheers,
	Leandro
