README, install.sh: imsd 1.0.0 finds the P-CSCF itself, the setup section goes

imsd 1.0.0 reads the carrier's P-CSCF from the ims PDN at every start, so
the section that had every user find it with adb and write /etc/imsd.env
goes, as does install.sh's closing hint; the file remains for overriding
the address or naming one where the network gives none. The intro no
longer presents imsd as a preinstalled extra; it is linked where VoLTE is
listed.
