qrap: Handle case of PATH environment variable being unset
clang-tidy warns that in passing getenv("PATH") to strncpy() we could be
passing a NULL pointer. While it's unusual for PATH to be unset, it's not
impossible and this would indeed cause getenv() to return NULL.
Handle this case by never recognizing argv[2] as a qemu binary name if
PATH is not set. This is... no flakier than the detection of whether
it's a binary name already is.
