checkinstall needs to provide imagemagick

[suntong]

The --provides=imagemagick needs to be added to the following command:

https://github.com/SoftCreatR/imei/blob/3f3b31b87fae671f2eda428f0161cf1e14a2aa17/imei.sh#L739-L753

Without it, I'm getting:

$ apt-get install jhead
The following additional packages will be installed:
  imagemagick imagemagick-6-common imagemagick-6.q16 libjpeg-turbo-progs
  libmagickcore-6.q16-6 libmagickwand-6.q16-6 libturbojpeg0
The following packages will be REMOVED:
  imei-imagemagick libjpeg-turbo8

because:

$ apt-cache show jhead
. . .
Depends: libc6 (>= 2.34), imagemagick | imagemagick-6.q16hdri | graphicsmagick-imagemagick-compat, libjpeg-turbo-progs
. . .

Thanks
