[PATCH] tests: fix getpwnam and getgrnam

[Lukáš Zaoral]

The calls to these functions would always fail because the size of the buffer
was smaller than the minimum (170000) specified in the test implementations
of getgrnam_r and getpwnam_r.  Use test_get*_match directly because getpwnam
and getgrnam should never fail on ERANGE.

This commit fixes the following failure in the test/root/restore.test test:

[21] $ chown bin passwd -- failed
chown: invalid user: ‘bin’        != ~

Fixes: 3737f000d3f17cd283f51eeacac21a71a3472053 ("use thread-safe getpwnam_r 
and getgrnam_r")
