make file install errors non-fatal, and xattr errors hidden 

user xattrs on tmpfs are not supported no non-grsec kernels,
and many times root fs is mounted without user_xattr. Thus
to allow things to go smoothly on non-grsec kernels xattr
unsupported errors are now hidden.

xattrs can be fixed still now with "apk fix --xattrs"
