Describe the issue you encountered

When I try to use gef-remote --qemu-user --qemu-binary ~/Desktop/<executable> localhost 1234, the command fails with the error

[!] Command 'gef-remote' failed to execute properly, reason: [Errno 17] File exists: '/tmp/tmp_k7juwvp/home/parallels/Desktop'

which seems to be a result of this exist_ok=False flag:

gef/gef.py

Line 11481 in 1b6f46a

target.mkdir(parents=True, exist_ok=False)

I also tested with the main branch (674c74d) and the problem still exists. Setting the flag to True solves the problem. If this is the correct fix, I'm happy to open a PR from my fork.

Do you read the docs and look at previously closed issues/PRs for similar cases?

Yes

Describe your issue. Without a proper reproduction step-by-step, your issue will be ignored.

1. Compile the minimalist test case.
2. Run it with qemu-arm64 -g 1234 a.out
3. gdb-multiarch -ex 'gef-remote --qemu-user --qemu-binary /path/to/a.out localhost 1234'

Minimalist test case

// compile with gcc -fPIE -fpic a.c
int main(){ return 0; }

Additional context?

No response

Why does this directory already exists? If it's a correct behavior to mkdir this directory multiple times, then I guess your fix should be good :)
