gnu: sendmail: Install executables to $prefix/sbin and $prefix/bin directories.

Currently "sendmail" installs executables to $PREFIX/usr/sbin and
$PREFIX/usr/bin directories. This patch changes them to $PREFIX/sbin and
$PREFIX/bin respectively. Also this patch fixes broken symlinks in
$PREFIX/bin and updates package definitions that use old sendmail paths.

* gnu/packages/mail.scm (sendmail): Set new paths.
 [arguments]<#:phases>{replace-/usr}: Remove /usr prefix.
 [arguments]<#:phases>{post-install}: Fix broken symlinks
 [arguments]<#:phases>{configure}: Set paths without /usr prefix.
* gnu/packages/mail.scm (claws-mail): Use new sendmail paths.
* gnu/packages/version-control.scm (python-git-multimail): Use new
  sendmail paths.
