[MachO] Remove redundant bounds check (#100176)

The condition was duplicated, the correct one for this message would
have been `ImportsEnd > SymbolsEnd`. However, this is a subset of
`ImportEnd > Symbols` (since `Symbols <= SymbolsEnd`), so it can be
removed altogether.

I made this thinko in 686d8ce.

Note that that change wasn't intended to be permanent, and served as a
quick stopgap to facilitate testing chained fixups in LLD before Apple
upstreamed their implementation.

Fixes #90662
Fixes #87203
