Fixed issue when link to itself could remove restored file without backup:
chunk1: fixed bug in sed call, when link to itself made whole source path to disapear (visible only for links into itself)
chunk2: ignoring any operations above jre-abrt (jdk7 specific)
chunk3: use mv -f rater then rm + mv (consequences?) to avoid overwrite, when source do not exists (is not needed when jre-abrt is skipped, but imho is safer)
