On musl _PATH_MOUNTED is defined in paths.h, not in mntent.h, which
causes compilation errors:
storage/storage_backend_fs.c: In function
'virStorageBackendFileSystemIsMounted':
storage/storage_backend_fs.c:255:23: error: '_PATH_MOUNTED' undeclared (first use
in this function); did you mean 'XPATH_POINT'?
if ((mtab = fopen(_PATH_MOUNTED, "r")) == NULL) {
^~~~~~~~~~~~~
XPATH_POINT
Fix this including paths.h if _PATH_MOUNTED is still not defined after
including mntent.h. This also works with glibc and uClibc-ng.

Well, in fact glibc has the _PATH_MOUNTED defined in paths.h too but
only thanks to mntent.h including paths.h (to define deprecated MOUNTED
macro) we are not hitting error there. Therefore, we can and should
always include paths.h. IOW, those ifndef-s can be dropped.
