fairphone-fp2: file does not exist error during initramfs-extra creation

When including mesa in the initramfs-extra (!1625 (merged)), then the fairphone fp2 reports the following "file does not exist" errors. This is just cosmetic, as @z3ntu who owns the device, reported that it boots anyway and mesa from the initramfs works as it should to display osk-sdl. We decided to not block the MR because of this.

How to reproduce:

• checkout !1625 (merged)
• pmbootstrap zap -p
• pmbootstrap init
  • select fairphone-fp2
  • select mainline kernel
  • select UI=none

I'm wondering... maybe ldd /usr/lib/libEGL.so would be helpful in this situation?
