std.os.linux: fix syscall argument width for mipsn32 and x32

Browse Source 
This required a thorough audit of every syscall wrapper in std.os.linux, so
while I was here, I fixed some minor arch-specific bugs, improved some types,
simplified some casts, and deleted some dead code.

Note that lseek() in particular is still broken for n32 and x32 after this
commit; this wrapper will require some special-casing in the arch bits due to
its unusual return type width.
