[dak/master] fix removals rss feed when there are fewer than 16 removals

[Mike O'Connor <stew@vireo.org>]

tools/removals.pl was making the assumption that at least 16 removals exist in
removals.txt.  If there are not, it creates and rss feed with with bogus empty
removals to pad the output to 16 entries.  This patch removes this false
assumption.
