WMaker: removed use of dangerous RETRY macro in GetCommandForPid for Linux (Coverity #50267)

As pointed by Coverity, the function GetCommandForPid did use a macro
'RETRY' for the 'close' of file descriptor, which is not correct because
on success the function 'close' does not reset errno, and in case of
failure the file descriptor is not more valid anyway.
