MSP-11368 MSP-11143 Remove fastlib as it slows down the code loading process. From the previous commit, the mean loading for `METASPLOIT_FRAMEWORK_PROFILE=true msfconsole -q -x exit` was 27.9530±0.3485 seconds (N=10). The mean after removal of fastlib was 17.9820±0.6497 seconds (N=10). This means an average 35.67% reduction in boot time.
