#68820: Upgrading specific port ignores epoch

 While testing that the recent rollback change for `openssl3` worked as
 intended, I found that it did not when applied to the individual port.

 With the recent change temporarily removed, I repeated the bad upgrade to
 `openssl3 3.2.0`, which worked as intended:

 {{{
 MacPro:macports-ports fw$ sudo port upgrade openssl3
 --->  Computing dependencies for openssl3
 --->  Fetching archive for openssl3
 --->  Attempting to fetch
 openssl3-3.2.0_0+universal.darwin_13.i386-x86_64.tbz2 from
 http://packages.macports.org/openssl3
 [...]
 }}}
 I then unremoved the recent change, and checked the "outdated" status,
 which worked as intended:
 {{{
 MacPro:macports-ports fw$ port outdated
 The following installed ports are outdated:
 [...]
 openssl3                       3.2.0_0 < 3.1.4_1  (epoch 0 < 1)
 [...]
 }}}
 But a plain upgrade of `openssl3` didn't work:
 {{{
 MacPro:macports-ports fw$ sudo port upgrade openssl3
 --->  Scanning binaries for linking errors
 [...]
 }}}
 So had to force the issue:
 {{{
 MacPro:macports-ports fw$ sudo port -n upgrade --force openssl3
 --->  Fetching archive for openssl3
 --->  Attempting to fetch
 openssl3-3.1.4_1+universal.darwin_13.i386-x86_64.tbz2 from
 http://packages.macports.org/openssl3
 [...]
 }}}
 It may well be that a plain `upgrade outdated` would have worked, but this
 usage should have worked as well.

 Note that this particular case only applies to the OS versions affected by
 the rollback, meaning <10.14, though I suspect that the general problem
 applies to any case where an epoch bump is being used for a version
 downgrade.
