build: Distinguish libini_config version checks

Use separate shell variable name prefixes for checks of separate
libini_config versions, as repeated invocations of PKG_CHECK_MODULES
with the same prefix are not generally supposed to have an effect.

Otherwise only the checks before and including the first one defining
both *_CFLAGS and *_LIBS variables will be done and all that follow will
assume success. This happens on RHEL6.5, where both "pkg-config
--cflags" and "pkg-config --libs" for ini_config produce non-empty
output and successful check for v0.6.1 results in incorrectly successful
check for v1.1.0.
