perf annotate: Do not ignore call instruction with indirect target

Do not ignore call instruction with indirect target when its already
identified as a call. This is an extension of commit e8ea1561952b ("perf
annotate: Use raw form for register indirect call instructions") to
generalize annotation for all instructions with indirect calls.

This is needed for certain powerpc call instructions that use address in
a register (such as bctrl, btarl, ...).

Apart from that, when kcore is used to disassemble function, all call
instructions were ignored. This patch will fix it as a side effect by
not ignoring them. For example,

Before (with kcore):
       mov    %r13,%rdi
       callq  0xffffffff811a7e70
     ^ jmpq   64
       mov    %gs:0x7ef41a6e(%rip),%al

After (with kcore):
       mov    %r13,%rdi
     > callq  0xffffffff811a7e70
     ^ jmpq   64
       mov    %gs:0x7ef41a6e(%rip),%al
