tty-clock + inxi added

Hi buddy,
Two new packages.
About tty-clock-git, I added <code>hostmakedepends="pkg-config"</code> because it seems to be needed in the <code>Makefile</code>. I'm not sure about the license too.
"close #139"
And for inxi, it has the following dependencies:
<code>   bash >=3.0 (bash); df, readlink, stty, tr, uname, wc (coreutils); gawk (gawk); grep (grep); lspci (pciutils); free, ps, uptime (procps); sed (sed)</code>
If I'm not wrong, they are all included in the base system, except pciutils.
"close #141"
See ya later.
