[PATCH] fix warnings

[Mikulas Patocka]

This patch fixes compile warnings

* src/filemanager/filegui.c defines macro STATFS but it doesn't use it, it 
uses statfs function instead.
This results in a warning because statfs has this prototype
"int statfs(const char *path, struct statfs *buf);", but we pass "struct 
statvfs" as an argument.

* ESC_CHAR is already defined in /usr/include/langinfo.h, so undefined it 
to avoid warning
