Amir Masoud Abdol 1bf144ba78 Resolve an issue with detecting GSSAPI on macOS
Spack, like VcPkg, sets the `CMAKE_FIND_FRAMEWORK` to `LAST`, as a
result, similar to VcPkg, when Spack is used, FindGSSAPI opts for
`gssapi_krb5` which is not what we want. By dropping the `gssapi_krb5`
from the list of alternative names we can resolve this without much
tinkering with internals of these package managers.

Pick-to: 6.5 6.6
