Subject: [PATCH] setfiles: Do not abort on labeling error

Commit 602347c7422e ("policycoreutils: setfiles - Modify to use
selinux_restorecon") changed behavior of setfiles. Original
implementation skipped files which it couldn't set context to while the
new implementation aborts on them. setfiles should abort only if it
can't validate a context from spec_file.

Reproducer:

    # mkdir -p r/1 r/2 r/3
    # touch r/1/1 r/2/1
    # chattr +i r/2/1
    # touch r/3/1
    # setfiles -r r -v /etc/selinux/targeted/contexts/files/file_contexts r
    Relabeled r from unconfined_u:object_r:mnt_t:s0 to unconfined_u:object_r:root_t:s0
    Relabeled r/2 from unconfined_u:object_r:mnt_t:s0 to unconfined_u:object_r:default_t:s0
    setfiles: Could not set context for r/2/1:  Operation not permitted

r/3 and r/1 are not relabeled.
