fdatasync() patch for FreeBSD

Hi,

in the recent SVN trunk and emelfm2 0.6.2 release, you are using a
fdatasync() call to flush a file after writing. FreeBSD does not have a
that call implemented and according to the POSIX specs it does not
differ much from the fsync() call.

Can e2_fs_writeflush() be changed to use fsync() instead (or #ifdef'd
for FreeBSD) without any impact on the rest of the writing behaviour?

Attached you'll find a patch for src/filesystem/e2_fs.c, which unbreaks
the FreeBSD build.

Regards
Marcus
