Fixes #1976 - vmmap read /proc/$tid/maps instead of $pid/maps ( #1982 )
...
It turns out that GDB's `info proc mappings` reads $PID instead of $TID and there are cases where the /proc/$pid/maps file renders no content, for example when the main thread of a process exitted.
This then causes us to fail to render memory mappings and falling back to memory maps exploration which is actually bugged.
This was found out by a flaky test which I reported initially as broken Arch Linux CI build: https://github.com/pwndbg/pwndbg/issues/1976 but it turned out it is two bugs:
1) us not taking `/proc/$tid/maps` into account instead of `$pid`
2) vmmap exploration having a recursion error
This commit fixes the former and the latter is still unfixed.
I also reported this GDB behavior to their bugzilla in https://sourceware.org/bugzilla/show_bug.cgi?id=31207 - not sure if this is going to be considered a bug or a "correct behavior" but lets see.

fix: allow site installation without enforcing a venv
...
Currently the only way to circumvent the venv checks is setting an
environment variable. However, this is not sufficient for distro site
packaging:
- if the variable is not set, its a rather bad and unexpected user
experience to somehow magically set PWNDBG_PLEASE_SKIP_VENV
- if the variable is set globally as login shell profile, this means
skipping venv is always enforced which means if gdb is loaded with a
pwndbg gdbinit.py from a git clone, its rather unexpected to skip the
venv
This patch checks for a `.skip-venv` file alongside the `gdbinit.py`
which means for site installations that use de-vendored dependencies
like during distro packaging, this file can simply be touched. It would
skip the venv when pwndbg is loaded from the site installation but at
the same time would not skip loading the venv when pwndbg is started
from a git clone.
