Justin M. Keyes 9139bf81cf defaults: disable 'fsync'
ref #6725

fsync() is very slow on some systems.  And since the parent commit, Nvim
is smarter about flushing files at certain times (e.g. CursorHold),
regardless of whether 'fsync' is enabled.  So it's less risky to disable
'fsync'.

Profiling showed slow (2-4s) :write and :quit caused by fsync():

:quit
    shada_write_file(NULL, false);

:write + fsync
