storage: fix build with musl libc

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.
