This patch consolidates Linux getdirentries{64} implementation on just
the default sysdeps/unix/sysv/linux/getdirentries{64} ones. The default
implementation handles the Linux requirements:
* getdirentries is only built for _DIRENT_MATCHES_DIRENT64 being 0.
* getdirentries64 is always built and aliased to getdents for ABIs
that define _DIRENT_MATCHES_DIRENT64 to 1.
Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,
sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and
powerpc64le-linux-gnu.
* sysdeps/unix/sysv/linux/getdirentries.c (getdirentries): Build iff
_DIRENT_MATCHES_DIRENT64 is not defined.
* sysdeps/unix/sysv/linux/getdirentries64.c (getdirentries64): Open
implementation and alias to getdirentries if _DIRENT_MATCHES_DIRENT64
is defined.
* sysdeps/unix/sysv/linux/wordsize-64/getdirentries.c: Remove file.
* sysdeps/unix/sysv/linux/wordsize-64/getdirentries64.c: Remove file.
