vshadowmount and fuse3 : No sub system to mount VSS format

[PyBonnetainNesterenko]

Hello.

I have fuse3 (3.17.4) installed and detected by the configure script :

Building:
libcerror support: yes
libcthreads support: yes
libcdata support: yes
libclocale support: yes
libcnotify support: yes
libcsplit support: yes
libuna support: yes
libcfile support: yes
libcpath support: yes
libbfio support: yes
libfdatetime support: yes
libfguid support: yes
FUSE support: libfuse3

But when running vshadowmount, I still get the infamous No subsystem to mount VSS format message.

It seems vshadowmount.c only knows of libfuse (>= 2.6, < 3).

Installing (in parallel) libfuse (2.9) does not solve the problem, since fuse3 is checked before in the configure script.

Artificially hard failing the fuse3 check in configure script (line 56863) lets the fuse2 check be done and succeed, and vshadowmount works with fuse-2.
