shared/systemd: fix gettid() compat implementation shadowing function from glibc

On Fedora rawhide we get the following build failure:

    In file included from shared/systemd/src/basic/alloc-util.c:3:
    ./shared/systemd/sd-adapt-shared/nm-sd-adapt-shared.h:114:21: error: static declaration of 'gettid' follows non-static declaration

       34 | extern __pid_t gettid (void) __THROW;
          |                ^~~~~~

glibc supports now gettid() call ([1]) which conflicts with our compat
implementation. Rename it.
