[Benchmarks+Autotests] Fixed building with Qt5 and KWallet

Autotests: No longer move autotests binary to $root/bin directory
Autotests: No longer needed to specify NO_SYSTEM_DATAPATH define
[Benchmarks] Added AdBlockMatchRule benchmark
[AdBlockRule] Improve performance of rule matching with QStringMatcher

Use QStringMatcher instead of QString::contains in RegExpFilters.
QStringMatcher internally uses fast Boyer-Moore algorithm.
