[Toybox] [PATCH 06/10] lib/getmountlist: setmntent(), getmntent_r() and stpcpy() are not defined in bionic.

[Georgi Chorbadzhiyski]

Use getmntent() and strcpy() to simulate stpcpy(). This whole
code looks buggy. For example getmntent_r() uses uninitialized
FILE * parameter and the whole stpcpy() business looks strange.
