What Does This Do

SegmentAllocator is a functional interface that defines the allocate method. We were using allocateFrom, which is a default method introduced in a later version (after 22). However, we still allow the memfd writer to use FFM starting from 22, where that method is not available.

In those cases, we encountered:

java.lang.NoSuchMethodError
at servicediscovery.MemFDUnixWriterFFM.syscall(MemFDUnixWriterFFM.java:101)
at servicediscovery.MemFDUnixWriter.write(MemFDUnixWriter.java:46)

This PR replaces allocateFrom(str) with a simpler alternative that works consistently across versions.

Good catch - the JDK's own javadoc is confusing because SegmentAllocator says it is @since 22, but it was actually available several versions before Java 22 as a "preview" API :)
