See the complaint on #4039. This doesn't fix that particular
issue (it's somewhat unrelated), but does solve around
a file parsing problem reported by @void-in

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.
