perf annotate: Fix failure when filename has special chars
When filename contains special chars, perf annotate fails
with an error:
$ perf annotate --vmlinux ./vmlinux\(test\) --stdio native_safe_halt
sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `objdump --start-address=0xffffffff8184e840
--stop-address=0xffffffff8184e848 -l -d --no-show-raw -S -C
./vmlinux(test) 2>/dev/null|grep -v ./vmlinux(test):|expand'
Fix it by surrounding filename in double quotes.
