tools: do not segfault gimptool with source without extension. 

Since commit 58fa382001, gimptool would accept source files with
non-standard extensions when using known C or C++ compilers. This would
include source with no extensions at all.
When this happens, do not try to set a pointer to a non-existing dot
separator to '\0'. That obviously segfaults.
