ltrace: update to current master

Lots of fixes have been made to ltrace, including the ones for fixing a
build failure for MIPS architecture. Updating to current master will
allow us to re-enable this package for MIPS and also remove some
upstreamed patches.

At the same time we add a patch made by Jérôme Pouiller to fix a bug
introduced by 5ba9e10 ("Split type definitions from the bundled configs
into their own files"). Two new configuration files are not installed.
Therefore, ltrace fail with messages like :

/usr/share/ltrace/libm.so.conf:333: error: unknown type around 'ldouble
erfl(ldouble);

That patch has been sent upstream.
