Brian Gianforcaro 39f924a731 LibELF: Skip DynamicObject::dump() if logging isn't enabled ...

I noticed that we were populating this StringBuilder and then throwing
away the result while profiling `true` with UserSpace emulator.

Before:

    courage:~ $ time -n 1000 true
    Timing report: 3454 ms
    ==============
    Command:         true
    Average time:    3.45 ms (median: 3, stddev: 3.42, min: 0, max:11)
    Excluding first: 3.45 ms (median: 3, stddev: 3.42, min: 0, max:11)

After:

    courage:~ $ time -n 1000 true
    Timing report: 3308 ms
    ==============
    Command:         true
    Average time:    3.30 ms (median: 3, stddev: 3.28, min: 0, max:12)
    Excluding first: 3.30 ms (median: 3, stddev: 3.29, min: 0, max:12)
