sys-fs/squashfs-tools: fix build with musl

Add two patches: First patch is essentially from

https://github.com/plougher/squashfs-tools/pull/3

and gives a fallback for missing FNM_EXTMATCH.

The second patch is from

https://github.com/plougher/squashfs-tools/pull/9

and adds the missing include for the S_IF* constants.
