main/busybox: upgrade to 1.37.0

Status: Should work, boots and works fine on my machines so far. More tests would be appreciated.

Will probably merge this next week unless major issues show up.

---

Not a lot of big changes in this release, mostly code shrinks and bug fixes here and there. Hence, I don't expect too much breakage. Most patches applied as is and didn't require any changes either. Nonetheless, I rebased the entire patchset and removed patches that were backported.

The 0001-modutils-check-ELF-header-before-calling-finit_modul.patch should be superseded by an upstream modutils change which checks that if the loaded module file path ends in .ko and if not attempts to uncompress it first. Thereby preventing compressed modules to be passed to the kernel and causing a weird error to be emitted. Therefore, this patch was removed
