minicom: change upstream site, bump version

minicom: change upstream site, bump version

Minicom is now available on a git repository at:
https://salsa.debian.org/minicom-team/minicom.git
Main changes:
- RS485 support
- NLS support
- various fixes

So:
- change MINICOM_METHOD to git pointing to latest commit
- add MINICOM_AUTORECONF = YES
- add MINICOM_MKDIR_M4 to MINICOM_POST_PATCH_HOOKS because autoreconf
requires and existing m4 directory
- add host-gettext to DEPENDENCIES for AM_ICONV macro
- delete old patches since they became part of git repository as commits
- add new patch to check if RS485 is supported
- update tarball sha256 in hash file

Git shortlog of Minicom repository follows starting from version 2.7
since commit for 2.7-1 debian version is not present.
The only difference between version 2.7-1(debian) and 2.7 seems to be
a coding style change in src/config.c file that breaks every line into a
string like:
(
"aaa"
"bbb"
"ccc"
)
instead of:
(
"aaa\
 bbb\
 ccc"
)
