ipmid: fru-reader: Use timegm instead of mktime

timegm is the inverse of gmtime. Currently, we are missing UTC time with
localtime when converting between timestamp and time string. This is not
an issue when the localtime is the same as UTC.

This issue is detected when we change the timezone to PST/PDT with
https://gerrit.openbmc.org/c/openbmc/openbmc/+/58293
and the FRU EEPROM time does not match the expected Mfg Date anymore.

Required:
https://gerrit.openbmc.org/c/openbmc/ipmi-fru-parser/+/58446

Tested:
Fru EEPROM Mfg Time now is in the same (after timezone conversion)
between the raw data and FRU output.

Compile ipmid with default options:

meson builddir
ninja -C builddir

Compile ipmid with yocto defaults:

meson builddir -Dbuildtype=minsize -Db_lto=true -Dtests=disabled
ninja -C builddir

If any of the dependencies are not found on the host system during configuration, meson automatically gets them via its wrap dependencies mentioned in ipmid/subprojects.

Enable/Disable meson wrap feature

meson builddir -Dwrap_mode=nofallback
ninja -C builddir

Enable debug traces

meson builddir -Dbuildtype=debug
ninja -C builddir

Generate test coverage report:

meson builddir -Db_coverage=true -Dtests=enabled
ninja -C builddir test
ninja -C builddir coverage
