cmd/internal/buildid: skip over Mach-O UUID from buildid computation
With the "-B gobuildid" linker option (which will be the default
on some platforms), the host build ID (GNU build ID, Mach-O UUID)
depends on the Go buildid. If the host build ID is included in the
Go buildid computation, it will lead to convergence problem for
the toolchain binaries. So ignore the host build ID in the buildid
computation.
This CL only handles Mach-O UUID. ELF GNU build ID will be handled
later.
For #68678.
For #63934.
