[OE-core] [PATCH] sanity.bbclass: Add syntax check on MACHINE variable

[Baptiste DURAND]

MACHINE variable should not contain uppercase characters.

Having uppercase in Machine name can lead to this kind of error : (here Machine is set to nuc-E3815)
ERROR: initramfs-live-boot not found in the base feeds (nuc_E3815 corei7-64-intel-common corei7-64 core2-64 x86_64 noarch any all).
