The configure script shipped by screen uses the presence of `elf.h` and `-lelf`
as indicator for an SVR4 system which implies a `#define BUGGYGETLOGIN`.

The SVR4 `getlogin()` replacement function does not compile with a musl
toolchain and we do not want it anyway, so patch configure to remove the broken
SVR4 detection logic.

Add missing `os.h` include to `utmp.c` to pull in the required `utmp.h` header.
