[OE-core] [PATCH v2 3/8] bootimg-pcbios: make boot image file unique

[Ed Bartosh]

Plugin code uses boot.img file name for an image file. If there are
two partitions that use bootimg-pcbios wic breaks with an error
"file already exists: boot.img"

Made image file name unique by adding wks like number to it to fix
the issue.
