libpcap: no rpath for '${SYSROOT}/usr/lib'

Otherwise other packages that use libpcap will add '${SYSROOT}/usr/lib'
to their rpath.

tcpdump: version bump 4.1.1 -> 4.5.1

Just an update to the latest version. Cleanup configure options while at it and
enable crypto support again. It seems that's no longer broken.

git: use git remote rm for backward compatibility

In scripts/lib/ptxd_make_get.sh there is a git call for:
        git --git-dir="${mirror}" remote remove origin

This fails on git 1.7.10.4:

git: fetching 'https://git.gridpoint.com/git/gpec/linux-ec1k.git into '/home/jringle/ptxdist-src/git.gridpoint.com.git.gpec.linux-ec1k.git'...
error: Unknown subcommand: remove

   or: git remote add [-t <branch>] [-m <master>] [-f] [--mirror=<fetch|push>] <name> <url>

    -v, --verbose         be verbose; must be placed before a subcommand

fatal: remote origin already exists.

On git 1.7.10.4, the command is 'git remote rm', not 'git remote remove'

According to the git.git commit [1] that changed this,
rm is still support, just not advertised in help.
