Blind fix for Linux 32-bit builds
...which, according to
<https://lists.freedesktop.org/archives/libreoffice/2024-March/091666.html> "32
bit build failure (smb, narrowing)", started to fail with
> /<<PKGBUILDDIR>>/sal/osl/unx/file.cxx: In function ‘void osl_file_adjustLockFlags(const rtl::OString&, int*, sal_uInt32*)’:
> /<<PKGBUILDDIR>>/sal/osl/unx/file.cxx:71:26: error: narrowing conversion of ‘4283649346’ from ‘unsigned int’ to ‘int’ [-Wnarrowing]
> 71 | #define CIFS_SUPER_MAGIC 0xFF534D42
> | ^~~~~~~~~~
> /<<PKGBUILDDIR>>/sal/osl/unx/file.cxx:795:14: note: in expansion of macro ‘CIFS_SUPER_MAGIC’

etc. My Fedora 39 "Linux man-pages 6.05" statfs(2) man page explains about the
struct statfs f_type field of __fsword_t type: "The __fsword_t type used for
various fields in the statfs structure definition is a glibc internal type, not
intended for public use. This leaves the programmer in a bit of a conundrum
when trying to copy or compare these fields to local variables in a program.
Using unsigned int for such variables suffices on most systems." But the
underlying __FSWORD_T_TYPE looks like it is actually defined as a signed type in
/usr/include/bits/typesizes.h.
