Bootstrap crystal 1.4.1
R4308 was lucky enough to have been created 4 years ago, but has languished barren.
A previous attempt at bootstrapping was D1093. The task is much easier now, with no patching required.
The interpreter can be enabled when we update to v1.5.0 which will include a fix for an issue caused by glibc 2.34.
Test Plan: All specs pass. Also tested crystal eval and compiling a simple .cr file.
