hooks: cryptography: work-around for systems with musl libc

Add a work-around for resolution of path to OpenSSL 3.x shared library
on systems with musl libc (e.g., Alpine linux). Such systems do not
have ldconfig cache available, and due to oversight, the fallback
library search codepath in PyInstaller <= 6.6 assumes that the given
library name has no suffix.
