Fix -Wimplicit-function-declaration error with gcc 14.
In addition to the patch source, fix a header redirect warning.

```
shutdown.c: In function 'mnt_off':
shutdown.c:185:45: error: implicit declaration of function 'quotactl' [-Wimplicit-function-declaration]
  185 |                                         if (quotactl(QCMD(Q_QUOTAOFF, GRPQUOTA), mnt->mnt_fsname, 0, (caddr_t) 0) < 0) {
      |                                             ^~~~~~~~

Subject: [PATCH] shutdown: Do not guard sys/quota.h sys/swap.h and
 sys/reboot.h with __GLIBC__

These headers are provided by uclibc/musl/glibc and bionic so we can
assume they are not needed to be glibc specific includes. This also
ensures that we get proper declaration of reboot() API
