grubby-bls: fix corner case when a kernel param value contains a '=' 

If a kernel command line parameter has a '=' character, grubby fails
to update the options field in the BLS snippet, for example:

$ grubby --update-kernel=foo --args="bar=https://test?token="
sed: -e expression #1, char 30: unknown option to `s'
