bfd: aarch64: Fix BTI stub optimization PR30957
The instruction was looked up in the wrong input file (file of branch
source instead of branch target) when optimizing away BTI stubs in
commit 5834f36d93cabf1a8bcc7dd7654141aed3d296bc
bfd: aarch64: Optimize BTI stubs PR30076
This can cause adding BTI stubs when they are not necessary or removing
them when they are (the latter is a correctness issue but it is very
unlikely in practice).
Fixes bug 30957.
(cherry picked from commit 98b94ebb3ffe715fddde762bb3ee7fd6d972f233)
