Contribute back SPECS/ntp/Get-rid-of-EVP_MD_CTX_FLAG_NON_FIPS_ALLOW.patch to upstream NTP project?

[ngie-eign]

Describe the bug

The patch posted in SPECS/ntp/Get-rid-of-EVP_MD_CTX_FLAG_NON_FIPS_ALLOW.patch could/should be contributed upstream to the NTP project (it would benefit multiple downstream projects like FreeBSD, multiple flavors of Linux, etc).
I would love to contribute it back on behalf of this project, but I don't know what license the patch was released under and so (for legal reasons), I don't feel comfortable putting myself on the line to contribute back the change.
