All three uses of osl_getFileOSHandle have been removed again

...introduced with a64db11b "Add some non-public
API to be used by SvFileStream" and e541105b
"Use osl API to access files in the SvFileStream code" but subsequently
identified as dead code with ab02fa65
"callcatcher: update list," 05a8216d
"STAR_ENABLE_FILE_LOCKING was a secret," and
1d3483ed "Remove some unused code from
unusedcode.easy."
