While converting to binman for an imx8mq board, it has been found that building in the u-boot CI fails. This is because an imx8mq requires an external binary (signed_hdmi_imx8m.bin). If this file cannot be found mkimage fails. To be able to build this board in the u-boot CI a binman option (--fake-ext-blobs) is introduced that can be switched on via the u-boot makefile option BINMAN_FAKE_EXT_BLOBS. With that the needed dummy files are created.

v3:
- add CheckFakedBlobs() and print a list of faked files at the end
- add unittest
v2:
- pass allow_fake_blobs to ProcessImage()
- set AllowAllowFakeBlob() to images/entries
- create fake blob in Entry_blot.ObtainContents() when file is missing and creation is allowed
still missing:
- unittest
- option to set BINMAN_FAKE_EXT_BLOBS in Makefile via environment variable. With that we could simply set this env variable in the CI (gitlab-ci.yml) with adding support to buildman.

Please check that you keep to 80cols, except where it would split a string.
This is missing a few holes in test coverage. Did you try 'binman test -T' ?
If you are stuck I could fiddle with it a bit.
