legacy-support: update to v1.2.1

[fhgwright]

Also removes the now-unnecessary version holdback for OS 10.4.

Retains the -devel subport, since it's likely to be needed again in the not-too-distant future. At this time, the -devel and non-devel versions are identical, but the -devel version is still referenced to the commit ID rather than the version, for easier future editing.

Closes: https://trac.macports.org/ticket/68314

TESTED:
Tested both normal and -devel versions (currently identical) on 10.4-10.5 ppc, 10.5-10.6 ppc (x86_64 Rosetta), 10.4-10.6 i386, 10.4-12.x x86_64, and 11.x-14.x arm64.
Builds on all tested platforms except 10.5 ppc +universal. Passes all -universal tests.
Buildable +universal cases pass all tests, except for expected failures on 10.11-10.13 x86_64 +universal (i386).
