Matt Morehouse 056774d13b [libFuzzer] Make redirects happen in proper sequence. 
"> file" must come before "2>&1" to have redirection occur correctly in
all cases.  Fixes a regression on minimize_two_crashes.test.

Matt Morehouse e911a5d356 [libFuzzer] Remove const from ignoreRemainingArgs return value.

Matt Morehouse 04304d129b [libFuzzer] Encapsulate commands in a class. 
Summary:
To be more portable (especially w.r.t. platforms without system()),
commands should be managed programmatically rather than via string
manipulation on the command line. This change introduces
Fuzzer::Command, with methods to manage arguments and flags, set output
options, and execute the command.
