#3740: drawtext drops backslashes

Summary of the bug:
How to reproduce:
Create files for tests, with contents:
/tmp/tmp0:
{{{
testsrc,drawtext=text=TEST\\\\:fontsize=50:fontfile=/usr/share/fonts/corefonts/verdana.ttf:fontcolor=red
}}}
/tmp/tmp1:
{{{
testsrc,drawtext=text=TEST\\\\TEST:fontsize=50:fontfile=/usr/share/fonts/corefonts/verdana.ttf:fontcolor=red
}}}
{{{ffplay -f lavfi -graph_file /tmp/tmp0 -i nullsrc}}} gives correct
results - we have a backslash in the end of drawn text , but
{{{ffplay -f lavfi -graph_file /tmp/tmp1 -i nullsrc}}} gives no backslash.
The second variant with adding {{{expansion=none}}} works correctly.
The uncut console output:
