app-shells/bash: prefixify bashrc.d files, whitelist st-256color, drop [ef]grep aliases

The ebuilds that install "${FILESDIR}/bashrc.d/10-gentoo-color.bash"
were neglecting to prefixify it. That is, to replace instances of "/etc"
with "${EPREFIX}/etc". After reviewing the prefix eclass, I found it to
be wanting in all of its chief respects: interface, correctness, safety
and robustness. Consequently, I rejected the notion of using it on
principle. Instead, I elected to create a custom function, which is now
used to prefixify both "bashrc" and "10-gentoo-color.bash". Among its
virtues are that it writes an amended stream to the standard output,
which may be directly processed by newins.

Whitelist st-256color for Set Text Parameters support. Also, add it to
the list of terminals known to support colour.

Drop the egrep and fgrep aliases again. Previously, they had been
dropped by Mike Gilbert but were inadvertently re-introduced through my
being thorough rather than prudent. Given that both are non-standard, I
certainly have no wish to provide users with any additional excuses for
their continued use.
