pkg/report: remove alt title for BUGs

We used to use "kernel BUG at source:line" for BUGs.
Later we switch to "kernel BUG in function" as a better title,
but kept the old title as alt title so that the new titles are
merged with existing bugs.

Now it's causing issues: the following 2 reports got merged together:

kernel BUG at lib/string_helpers.c:983
Call Trace:
__fortify_strlen include/linux/fortify-string.h:144 [inline]
strlcpy include/linux/fortify-string.h:159 [inline]
init_names fs/gfs2/ops_fstype.c:385 [inline]
gfs2_fill_super+0x1226/0x27f0 fs/gfs2/ops_fstype.c:1187

kernel BUG at lib/string_helpers.c:980!
Call Trace:
 __fortify_strlen include/linux/fortify-string.h:128 [inline]
 strlcpy include/linux/fortify-string.h:143 [inline]
 __set_page_owner_handle+0x2b1/0x3e0 mm/page_owner.c:171
 __set_page_owner+0x3e/0x50 mm/page_owner.c:190
 prep_new_page mm/page_alloc.c:2441 [inline]

while they are unrelated.
A BUG in a common ignored helper will glue all reports together.

We added the alt title in Jan 2021 (de4e4f4d8b582).
All existing bugs should have been merged already,
so we can safely remove the alt title now.
