Subject: [PATCH] mender-device-identity: Check if file exists before reading

Mender on oragepi fails to run because identty script exit with error like:
/usr/share/mender/identity/mender-device-identity
cat: can't open '/sys/class/net/bonding_masters/type': Not a directory

Add check before reading type to avoid problems.
