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.
